This Evanescent Ocean of Red

How come the running never stops? The ceaseless pain of your memory.

Hiding amongst the humans forever. All the lies and guilt controlling Shoji's life seems endless. Until he meets a ghoul named Neko.
Shoji has never meet such a ghoul like her before. Her peculiarity and uniqueness draws her to him, and they instantly become friends.
Neko is the only person that can save Shoji from the surging darkness of the life he has made. She'll help him through his past and uncertain future.
Her tender words and sweet aura brings Shoji to realize his feelings for her. Except it seems Shoji isn't the only one Neko holds close to her. He learns of Neko's childhood friend, Juuzou, who seems a little too protective.
He later learns Juuzou has something in common with Shoji, but it isn't something he wants to share.
