Marie Rose and Honoka are profitable but hold no true relevance to the story. Raidou does, but he isn't profitable. That saddens me. For Ein, why not just give Ein's moveset to Hitomi's father? The dude is jacked and large, and DOA needs more large buff men!
I was looking up old Tengu footage and I found your channel. Then I just watched some of your gameplay, from DOA2U to DOA5. However, I do recall seeing you once on DOA4 a long time ago.
