Rei Sakuma

Kukuku ♪ I am the leader of the idol unit UNDEAD, a group of demons of the night, dwellers of the darkness. Alas... Both my adorable little brother, Ritsu and I were born with a vampiric disease that makes us weak to sunlight. Thus, I stayed in and read many books, amassing a wealth of knowledge that could rival that of adults. A few years ago, I left for overseas in hopes of finding a cure for my and Ritsu's condition, and it breaks my heart that my beloved Ritsu now resents me for leaving him.
