In Type-Moon, he steps outside and gets picked up by Minamoto no Raikō, who takes him in as her adopted son...
...Boss Raikō, I thought of you as my big brother. I wanted to learn martial arts and slay monsters, but you want to be my wife?
He steps in to help someone and rescues a young lady kidnapped by a snake demon. Then she says her name is Kiyohime, that she fell in love with him at first sight, and that he has to marry into her family!
The oni girl who spends every day showing up to wrestle and drink with him is actually one of the Four Oni Kings, who rule a hundred thousand oni next door. Now she wants to drag him off to be her bandit bridegroom!
Listen, even if I die today, Minamoto no Kurou will never mooch off a woman. I'll die outside, I'll jump off this very spot, but I will never take a single bite of a woman's money...
...What's with all these crazy women? Boss Raikō, save me! Hngh, ahhhhhh!
