|Full Name||Makoto Washio|
|Friends|| Rokuro-Kubi (girlfriend)|
When he first appears he is a senior at college studying science and engineering. He met Rokuro-Kubi while she was working part-time with Neko-Musume at the school store. At first he believed she was a human girl named "Rokuko", but after he hurt his leg in a confrontation with Odoro-Odoro she stretched her neck to call for help, revealing to him that she was a yōkai. Rather than freaking out, Makoto finds himself unable to think of any other women after this, and the two begin dating soon after.
- Makoto is the first time the recurring human character in a Kitarō anime was a male.
