Not quite sure on the transfer and all boys part, but there's this manga. http://www.mangago.me/read-manga/monster_petite_panic/
it’s definitely not this one but it does look interesting so thank you for your efforts I’m going to go read this
Basically some kid transfers to a certain all boys school but apparently this school is for special students who have powers and are ( I think) demons.
