The art looks familiar, but I can't place it...

It's Takaku Shouko, I think.
But I don't know the title.

It's probably this one

It's probably licensed? I dunno, but there're like 3 volumes already, so I guess so ^^

Thank-you! :-) I saw someone ask about it on Crimson Spell... I recognized the artwork (because I just read Boku wa Subete o Shitte Iru recently) but I couldn't place it... As always, you are awesome. ヾ(☆▽☆)

No problem ^^ I've seen it before and also though it looks familiar, but couldn't recognize it immediately (I think the artwork changed a bit)

Thanks for your info, °˖✧◝(⁰▿⁰)◜✧˖° I put them in my album already, (❁´▽`❁)*✲ﾟ*
