Timeline isn’t gonna match up or make sense so don’t think about it. This was for an OC I didn't care enough to fully flesh out. Kinda sorta post-canon (all Hashira alive). Little OOC so don't think about that either. Might do a part 2 with background. She/Her pronouns (I'm sorry. I'm lazy)

Tomioka Giyuu isn’t what you would call, active. In fact, the thought of him having a life outside the Demon Corps never crossed the Hashira’s minds (mostly because they didn’t think he had one IN the corps either).

—

He was early. Extremely early, actually. Tomioka was not the latest Hashira by any means but, up so early was, off, to say the least. Shinobu noted this when saying her ‘hellos’ to present Hashira. Tomioka, of course, stood off to the side, not making an effort to interact with anyone aside from a simple “Good Morning.” Even for the ever stoic Tomioka this behavior was weird.

“I guess he remembered us after all.” Shinazugawa hissed coming to the group. It was true that the last three meetings Tomioka had missed (granted they’ve all missed meetings due to work but never three in a row) and the thought of Tomioka slacking off and getting off scotch free added on to Shinazugawa’s ever-growing list of reasons to hate Tomioka.

“It must have been a hard mission.” Kanaroji chimed in.

This didn’t sway Shinobu or Shinazugawa. Shinobu knew it couldn’t have been missions for the last three months, Tomioka hadn’t stopped by the Butterfly Mansion once, not even to get ointment for aches and pains. Strong as they are, the Hashira are not invincible. In fact Tomioka hadn’t been badly injured since last spring. Shinobu knew all this. Even outside of missions Tomioka had just been missing overall. It’s like the silence was even quieter without him there. She peered over to Rengoku and Himajima who looked notably tired well- as tired as they possibly could -as they both lightly chatted with amongst themselves. Tomioka would say something back to them and then go back to staring blankly at the porch.

“He’s finally starting to slack off.” Obanai hissed from up high, the group now noticing he’s been here. “I hope he doesn’t think getting here early will absolve him.”

“Obanai you don’t mean Tomioka got here before you?” Shinobu teased

With a fluster shifting of his eyes, Obanai chose to glare at Giyuu rather than return her gaze. “I saw him coming from inside. Maybe Master snapped on him.”

Though they all doubted Master Ubuyashiki would ever raise his voice, the thought did fill Shinazugawa with momentary joy.

With the final Hashira, Muchiro, walking into the garden it was only a matter of time before the Master appeared. With the opening of the door, everyone’s head snapped up and voices hushed. Shinobu snuck a glance at Tomioka who seemed slightly off. He stood a little too straight and struggled to not ball his fist. Obanai’s theory suddenly seemed more plausible.

—

With the meeting concluded you could practically hear the sigh escape Giyuu’s lips as he walked to the porch. He could feel all the eyes on him as he stepped up there only to be stopped by Hinaki.

“I have to ask that you wait here.” She said calmly.

“But me and Hiro-“

“OI! Have some respect Tomioka!” Shinazugawa yelled. He approached the porch. “Who do you think you are to go around ordering people?!”

He caught Giyuu’s glare from on high. His unchanging eyes shifting back to Hinaki only angered Shinagawa more. “He’s looking down on me,” Shinazugawa thought this an act of war.

Glaring back at him, he said “It’s one thing for you to skip meetings but to disrespect the Master’s family.”

“I’m not disrespecting her, I had a question.” Giyuu replied plainly. He was feeling slightly annoyed and very fearful now. This was not how today was supposed to go. He turned back to Hinaki, “Please, we must be on our way-“

“You bastard.” Shinazugawa was already reaching to pull Giyuu off the porch (not wanting to beat him on the porch, that would be disrespectful). Giyuu was ready to draw his sword when the sound of footsteps alerted them all. Out from the door burst Kiriya and another small child. They maneuvered around Giyuu and Hanaki before Kiriya had tripped taking the small boy with him. Before they could launch themselves off the porch Giyuu caught one under each arm and held onto Hinaki’s collar to keep her from falling over.

He set the children down gently, “Forgive me please, Ubuyashiki-san.”

“No, thank you Tomioka-San.” Hinaki replied, graceful as ever. Lady Ubuyashiki was quick behind them to collect her son. Giyuu apologized once again.

“Hiroshi,” Giyuu turned back to the small boy. He stood slightly behind Kiriya with his head low in shame. Giyuu knelt down, “You should apologize to Lady Ubuyashiki and Hinaki.”

Big blue eyes filled with embarrassment the boy complied. Lady Ubuyashiki smiled kindly, “Please be careful next time you return.”

“He can come back?” Kiriya asked

“As long as Tomioka is okay with it.” She smiled kindly

“Of course.” Giyuu replied as the three kids waved off. “Come on, we’re going home.” The boy followed behind Giyuu quietly. He had a small round face and wild black hair sticking out in all directions. Following along, Hiroshi started to sniffle and finally stopped on the bottom step, tugging on Giyuu’s haori.

“What’s wrong?” Giyuu asked

“I’m sorry Papa.” He cried softly as Giyuu picked him up in his arms trying to soothe the boy.

“It’s okay Hiroshi, I know it was an accident but there’s two of you and only one Hinaki. She could have been hurt. Please be more careful.”

The boy nodded sniffling into his fathers shoulder.

The remaining Hashira stared in astonishment at the action. By the time he got his son to calm down Giyuu had finally noticed that he never left the garden and out the front of the home as intended. Still holding Hiroshi, Giyuu bowed his goodbye and left the garden. Before the rest of Hashira could finish processing what just happened Rengoku and Himajime also left quietly behind him.

—

The next meeting came about a month and a half later. This time Giyuu entered at his normal time with Muichiro coming afterwards. He actively stood apart hoping they all would have forgotten (they didn’t), and suffered silently as the many eyes bore into his head.

It wasn’t just Giyuu, Shinobu was also shooting her glance to Himejima and Rengoku. Himejima was holding up well (surprisingly) but Rengoku was going to pop. Unbeknownst to everyone else, Tengen spent the last week and a half trying to break whatever secret Tomioka had about the same child out of him. An unstoppable force and an immovable object and all that.

Giyuu was silently praying for this meeting to end soon and end this mental game all the Hashira were taking part in. He had already prepared an exit tragedy to get out with the least amount of questions. He looked at Rengoku and Himejima. The game plan was set and they just need to be ready to go.

You could feel the tension ease when Master Ubuyashiki called the meeting to a close. They all stood quietly, paitiently waiting for him to go inside before all hell broke loose. And just as the door closed Lady Ubuyashiki called out, “Tomioka-San. A word please.”

Rengoku was screaming on the inside as Giyuu looked over to him briefly. Tengen hardly waited for Giyuu to take a single step, “How come you two got to know but we didn’t?”

“A secret child Tomioka?” Shinobu called out “You must not like us if we didn’t get to know.”

“It’s not that…” Giyuu finally broke his silence. He reached for the door when it suddenly swung open and the little pitter of footsteps was heard. Giyuu jumped back and was quick to catch the small figure barreling towards him, “Hiroshi!? What are you doing here?”

“Mama hurt her feet.” Hiroshi replied like it was obvious. All heads snapped to the door and out stepped a woman on a pink kimono.

“(Y/N)?” He looked surprised.

“Ah, Giyuu!” She peered up walking over to him

“What happened?” He stepped closer to hold onto her waist.

“Just some sores and aches. Lady Ubuyashiki has been so kind.” She turned to both of them “It’s been in honor in your presence.”

“The pleasure is ours, Lady Tomioka.”

And that’s what broke the string holding all together. The family wordlessly walked off the porch and headed to leave..

Shinobu called out “T-Tomioka?!”

“Yes?” Said (Y/N) and Hiroshi as all three turned to face them.

“Oh! Rengoku-San, Himajime-San! So good to see you both.” (Y/N) smiled

Himejima finally exhaled as both men walked over to greet (Y/N). Both of them gave Giyuu an apologetic look. Hiroshi looked over their shoulders to the remaining Hashira still in a daze. Looking at them side by side there was no denying it. Hiroshi is identical to Giyuu, just smaller and with the cutest round face that Mitsuri just had to gush over.

“You are so cute! Like a mini Tomioka!” She squealed.

“Your hair looks like mochi!” Hiroshi stayed proudly. “Mama, can we get mochi!”

(Y/N) smiled, “That sounds like our que. It was an honor to meet you all.”

The family walked out the garden, with Rengoku and Himejima sneaking out with them.

“What the fuck just happened?” Shinazugawa broke the silence.

—

The next meeting was well over two months and the pillars were determined to not let Giyuu go without answers. Especially since he’d recently had to heal up at the Butterfly Mansion while Shinobu was out. Before he could even think of leaving they had him cornered, Obanai watching over Rengoku and Himejima.

“When were you gonna tell us you were married?!” Uzui shouted

“No one asked and I’d rather have a small wedding…” Giyuu answered plainly.

“What about your ring then?”

Giyuu pulled down his collar to show a silver ring on a chain tucked into his undershirt.

“How did you two find out then?” Obanai hissed.

“Tomioka requested I accompany him on a mission so he could be home earlier,” Himejima stated.

“I had an urgent matter with the Master and happened to meet them all as they were leaving.” Rengoku said.

“Wait so Master knows too?” Mitsuri asked

“Yes, they were at the wedding.” Giyuu replied.

“You are unbelievable.” Shinazugawa muttered. “How were you able to get married?”

Giyuu didn’t seem to have an answer. It’s something he thought to himself many times but when (Y/N) smiled at him he always forgot about it. Before he could try to answer, he heard (Y/N) calling out to him. The Hashira were surprised to (Y/N) walk up in a demon slayer uniform and golden checkered haori. She smiled and bowed to the Hashira, “Hello, I hope I’m not interrupting.”

“No, I'm done here.” Giyuu replied.

“Wait, Tomioka!” Shinobu called as they turned to leave.

“Yes?” They both answered to Shinobu’s annoyance. They did it again.

(Y/N) nudged Giyuu forward as she assumed they meant him. Uzui cut in, “We only wanted to officially meet you, Lady Tomioka.”

“Oh!” (Y/N) smiled “I’m honored to meet you all, I am Tomioka (Y/N), (Y/N) is fine.”

“It's so good to meet you! How long have you and Giyuu been together?” Mitsuri asked, the only genuine person in all this.

“I’ve known him since I joined the Corps, we met while I was on my way to a job, it was in separate areas but we met up on the way back.” (Y/N) answered recalling their younger years.

“We’ve been married for five years.” Giyuu answered. The Hashira took note that their son looked about that age. It took all of Uzui’s strength for him to not comment on it.

“How sweet!” Mitsuri cheered “I had no idea you had such a happy family Tomioka!”

“We try not to talk about it,” (Y/N) smiled. A lot more open than Giyuu but (Y/N) also enjoyed their privacy. “Up until now, only Master Ubuyashiki knew. Hiroshi and Kiriya became good friends.”

The Hashira had a million other questions but they tethered on inappropriate or just plain mean. Out of respect for Lady Tomioka, they held themselves together. The strangeness of the situation wasn’t lost on either of them. They were happy though. The couple said their goodbyes and turned to leave. The Hashira saw the tension lift off Giyuu’s shoulders as he smiled with his wife.

“Why must we question Tomioka,” Himejima spoke once they left. “Lord Uzui is married with three wives.”

“Yeah but that was before he joined the corps,” Sanemi said “We didn’t know him then, we know Tomioka- barley. He’s a fucking buzzkill and he has a sweet woman that not only married him but slept with him at least once!?”

With those “graceful” last words they parted for the evening.
