1. Mars - Generally I read any genre so some cliches just repeat and repeat. I stumbled upon this gem accidently and reread several times already.
2. Boku no Chikyuu wo Mamotte - Same reason as above though at first I was relucant to read it because of it's anime adaptation.
3. Holyland - Favorite genre with stunning story and characters. This manga never ceases to amaze me and make me hooked on his manga.
4.Watashitachi no Shiawase na Jikan - First manga to make me cry, I'm sucker for painful, angsty stories
5.Dokuhime - same reason as above
