2D vs 3D who will win?! This is a rare vanilla work from DATE, though all his works have some sort of depressing element to them. This one is depressing by being too real though the story is still cute.

I think this will be the last DATE work I translate until we get a sequel to Tanin Ni Naru. The other untranslated works are just too depressing...

Rereleasing this with onii-chan% as I never realized how serious some people take their onii-chans
I'd also like to note that this is not incest. It clearly states on page 4 that she is just a girl that has lived in the neighborhood for awhile. She calls him onii-chan to try to appeal to his fetish like the girls in the ero-games he plays.

Thanks a lot, @LearnJPwithH !!!

Untranslated manga suggestion, one of early DATE's original works:

One of those rare instance where Date does vanilla...

Well he began his mind control/possession fetish in 2012, so this is bit before that. You can even say its one of his last vanillas, then he went full licorice horror.

No way this is vanilla. The little sister is probably possessed by her evil uncle or something.

I am just waiting to see how this vanilla story spirals down into something disturbing or depressing. Maybe she leaves him for someone exactly as he described here. That would be a bit more fitting for DATE.

Nah, I think most guys just want a decent-looking virgin girl that would love--and care about--them, at the minimum.

When I saw DATE, I thought it would be more depressing garbage fire but nope! Pleasantly surprised that he/she could still write warm & funny vanilla.

Original release date: August 2011.

Sometimes, I really wonder what happened to these authors that would cause them to go from vanilla to that.

Not that I mind, but it would be interesting to know.

What 's this!??!

Vanilla DATE

This must be a dream.

A vanilla made DATE?! If this wasn't from 2011 I would be totally expecting a not so vanilla sequel showing us what was really going on.

No wonder he thought it was the bottom (literally) hole, the top was invisible!
