"I want to save my first time for my little sister!"
That was the declaration of a cross-dressing siscon, made amid a storm of protests.
Somehow, he got roped into a Holy Grail War with a name that had been used to death.
He wasn't happy about it, but there was no changing the facts. He endured scenes where he could die at any moment, holding on only because he wanted to live for his little sister.
"Anyone who lays a hand on my little sister is my enemy."
