青い赤目 (Aoi Akame, Blue Redeye)
|Effect Reaction|| • Cat: Drawn towards Madotsuki
• Stoplight: Freezes
This creature is composed of a very dark blue mass with a dark blue-green face and black eyes, each with a red pixel for a pupil. It is found before reaching Big Red.
The Alley Demon roams within the lane that the player cannot access without hacking, so interaction is normally impossible. Nonetheless, it displays normal reactions to the Cat and Stoplight effects, but not the Knife effect.
