REDROP CANT KEEP GETTING AWAY WITH IT

I want to see Daikoukuten (the real god not the female mice) as a Servant so much with Mahakala and Okuninushi as his two different sides.

Another in the event in the future, but gonna be hard to explain on summoning them unless there's exempt like Tamamo.

A rare common, easy to find and trace case of syncretism in fgo. In this case they're referring to Shiva, who's also known as Mahākala in both hinduism and Buddhism, and who then became known as Daikoukuten in Japan.
