Hey, quick question. Which wizard is going to get impaled by Akira's claymore first, and why do you think it'll be her?
I'd prefer none, but I'm probably leaning towards Chinami...
In Chinami's Chapter 4 'Holden Caulfield' Event, it seemed like Chinami is the Maya to Tsukasa's Noriko:
In Sensei's eyes.
He also later sees Tsukasa as Noriko again:
I think we all are aware of what happened back during the tutoring days, Sensei's fascination with Maya, and Noriko's cuckold curse.
I can also see Chinami...well, she wants Sensei to stay with Chika:
She's already dedicated probably most of what life she's had to making Chika happy, hence Chinami's "Chinami Talk". She's also smart enough to know she isn't exactly got a high chance of even finding someone to love, and she'd probably rationalize it'd be a way to keep Sensei around, and her sister if not sisters (counting Yumi) happy-ish. (As long as they don't find out)
There's also how Sensei apparently had a habit of blacking out on Maya, so...trying to think "positive".
Nao-chan seems like she could probably handle herself if it came to it, but we'll see. Tsukasa may simply inherit Noriko's curse, but ngl, it'd be ironic if Noriko even gets cucked by a wizard that reminds Sensei of her...
