- Ryo's Introduction
- Near the end of the OVA, Akira falls from the sky and lands, naked, in the middle of a giant, Amon-shaped hole in the ground. Given how serious the rest of the OVA is, this is hilarious.
- In the first volume, when Ryo tells Akira to put on the demon mask.
Ryo: Put it on.
Akira: (beat) I-I'd rather not.
Ryo: (annoyed) Put it on.
Akira: Maybe next time?
Ryo: Put it on!
- Before they enter the demonic rave club, Ryo is seen smoking a butt.
Ryo: Oh this? Its laced with drugs.
