The main manga is Ze! One of my favorites, you have to read it before reading the extra Chapters here! It's long but so.worth.it. Believe me ;)
Like AnnaX said, the main story is "Ze". It's a long but very beautiful and wonderful story and you will understand better the relationship between all the characters, especially Moriya/Ryuseei and Genma/Himi. Have a great reading ;-)
Is there a prequel story of Ryuusei and Moriya? Also, a prequel story of Himi and Genma?
Any link for it? (=・ω・=)TIA :)
