"You're adorable."

"Thanks! You're - amazing."

"I agree but I'm not sure what amazing thing I've done so far."

"Just - being you. Kind and smart and confident and all."

"Well in that case you're amazing, too."

Eeeeee! The only appropriate response is clearly more kisses.

So many of those!

After a while of kisses, Tetsuma asks, "So do you want to learn genjutsu? I'm not very good at it, but there's all sorts of fun to be had at higher levels."

"Yeah, it sounds interesting and fun."

So they can go through basic genjutsu! ...Which is all that Tetsuma knows. Though it's enough for the general principles, and if you have a knack for it, genjutsu is the most flexible field. Tetsuma can make some fairly decent visuals but can't make them believable, and he only knows vague theory for the other senses.

Dayo picks it up on the first try.

That earns kisses. Highly impressed kisses.

Eeee "This is fun I like this!"

"Kissing or learning genjutsu?" Tetsuma teases, blushing.

"Both," he says, smirking.

Another kiss. "I'm having fun with both, too. It's great seeing you so excited."

"Your magic is great and everyone should learn it."

"I'd like to know more about why my world's so unusually unstable first - there might be some inherent problem with having that much power floating around - but yeah."

"Well... it might be something cultural? The way your world is organised is... strange."

"I... don't know. The thing is, I think everywhere is in a similar state of war, not just the Elemental Nations, but I've never been anywhere else."

"...yeah okay that's—at least suggestive."

"I used to have a friend who had all these wild conspiracy theories, that somebody was somehow sabotaging peace, but... A simpler explanation is that something's wrong with shinobi, or at least with average or even just worst-case human nature when given that much power."

"I'm not sure 'that much power' is the right metric, though? It doesn't look like this place's magic is less—powerful than yours—perhaps less versatile?"

"I'd imagine the ley gets in the way of launching too many stupid wars, but yeah this place does look like it has some fairly powerful magic."

"It'd be easier to draw conclusions if we had, like, history books or something."
