So Moriyama-senpai is the big sis from Game right? Always the same thing when a new Jin comic appears, gotta refresh my memory by going through several anthologies and put all the pieces together!
I've written this before, but reading her work I always draw diagrams.

And they're usually interested in each other at cross purposes.
