Tohka's the star of the show this time round, but she's wrestling with her own issues ? old memories of her parents, and a promise to a friend that she wasn't able to keep...

“You're right. There's a reason we need to get back... even if it means crawling home on our hands and knees.”

“Let's meet up again someday... if we're still alive.”

And introducing Sengoku Ayame - Sengoku Ichiru's brother, and a handler at St. Aile's:

“If takin' her in alive's too much of a challenge, just get rid of her - I don't give a damn. I wanna see this mess cleaned up.”

What answers will Tohka find? She has the truth in her sight...
