3 actually. Shiho is part of the reason Miho wanted to transfer too. If I'm not too wrong, that is.
And damn! This would be all the more reason that double victories are at least twice as precious.
You're correct, though I wouldn't say she was involved with this battle in particular. I guess it depends on interpretation, how much involvement 'counts'.
I just LOVE this doujin. It's a plausable reason for Ooarai discontinuing its Tankery program, and is definitely a good backstory for Yoshiko.
Definitely agree with LoweGear about it being a headcanon.
