so the manga (possible anime aswell) main character was a ditzy..but had good reflex str etc.

the other charz were he lazy but strong brother who lived on island with her and raised her

now the ezy part

the teacher came to the island and i dont remeber why but she did and she has the ability to use vine (morning glory i think) at will her assistant back at the school draws really fast
the headmaster of school is actually a little girl gives main character a impromptu exam(without telling her) she ends up fighting a teacher who can harden his skin like steel but main chracter is reckless and shatters his will after repeatedly punching him and so his power faulters and sht wins (albiet fukd up hand lol).. long post all ove place im sorry doing this form phone and it hates e

nvm found it manga is called ESPRIT ty and srry
