Toritan
Inusaki is just a self-proclaimed detective who's really working as more of a fix-it who happens to have the ability to talk to birds. One day, he ends up talking to a cool crow he nicknames Kuro, and before he knows it, he's fallen for a crow! When the crow rejects him, his landlady' son, Mitsuru, ends up checking on him, and soon his feelings shift to the cute high schooler Mitsuru who he's sure has a girlfriend already. But Mitsuru has a secret of his own. Cute. No trigger warnings.
Count H
A sequel to Count 0, Agatsuma and Misono are now an established couple. Misono is in college while Agatsuma has recently passed the police exam, but Misono worries that his ability will put too much pressure on him in this situation. Through all this, Agatsuma meets Misono's teacher and finds he's yet another person with a rare ability. I was happy to see more Agatsuma and Misono, but the teacher subplot and the information about abilities didn't really answer any questions so it ended up just kind of being in the way. Trigger warning: violence.
