Nikonikoni's Manga

I don't really know how many manga i've read today but this one remains best. Looking forward what would happen in nxt chaps while imagining myself what would happen lol.

By the way does anyone here know the story about a guy that sleep for more than 200 or 2000 yrs and become child again.
After that he met the demon(?¿) Girl He saved before. Then theres a rich family on where the girl lives, the young boy want to play with him and he just ignore it while reading books dodging the guy.Also he has an extraordinary eyes like purple.I've read it but forgot cause i dont write down the name on list.
