Okay, the manga I'm looking for is one I read a few years ago, I know I'm off to a bad start with that line, but please bear with me, sorry for the bad pun.

The main character's ability to to cancel the special abilities of other characters in the series, but he only realizes it in true shounen fashion, ie, needed to protect someone.

The heroines in the series are based off of fairy tale girls, main two I remember are Kaguya hime and
Sleeping beauty. Kaguya, if memory serves, could manipulate gravity, while Ibara, sleeping beauty, could materialize thorns, and got stronger as she went longer without sleep.

The last, and most important, detail I can remember is that the main character is the heir to his original home country, he had to leave for reasons as a very young child, and he has a brother who calls himself, again, if memory serves,, Jiro, as he dislikes his chuunish name..

If anyone can help me with this, I will help them search through a sea of doujin of their choice, or send them some cookies.

Please help!

Hmm I'm not sure but is it Otogi Taisen Fantasma ? I did a google search with "jirou kaguya ibara" and that came up 😀 .

THAT IS IT! THANK YOU!
