Harunan aka the girl who couldn't sing to save her life becoming a musical actress is a plot twist and probably a proof that H!P doesn't always chose bad singers but instead don't want to give the girls proper singing lessons.
These two weren't in MM together for very long, but they were absolutely on the same page for playing off of each other (with Yokoyan taking the initiative)
Really good combo
(For potential link rot purposes, this is Yokoyan and Honey announcing Satoyama events starting in October 2018, and then shilling a packaged curry)
10ki will always be my favourite gen for their “enemies to nakamas” dynamic. That first meeting where 3/4 was hiding with varying success the thought “really? HER? FML” and the last one going “ehehe, Maa-chan’s gonna die~ <3” was just comedy gold.
Nowadays I feel like the girls interact with their seniors and KKS gen mates more than playing off of each other.
