i think this is a oneshot from jump sq. can anyone tell me what the name of it is or where i can find it? it looks interesting...

thanks in advance

It's called Mutsu to Yozora by one Hiraishi Sawa (I think). It was a contest, so it's a first-timer - you're not gonna find the mangaka in the database here unless/until it gets scanlated. I don't know where you're gonna find it, though.

Thanks though, at least I know the name so I can look out for it.
