Jitsu wa...

Jitsu wa... ("I am...") is a Harem Genre manga which began in 2013. It has been published in English under the title My Monster Secret.

Our protagonist, Asahi Kuromine, is an Ordinary High School Student who harbors a crush on the beautiful and mysterious Youko Shiragami. While he's usually unable to keep a secret or hide his feelings, he's managed to keep this crush a secret for years, but when he finally manages to find the courage to ask her out, he accidentally learns that she's got a secret herself: she's a half-vampire. Her father only permits her to study at school so long as her secret remains secure, so Asahi vows to keep her true nature a secret...and she's not the only one at school who is more than she seems.

This manga got an anime adaptation in 2015.
