Aojiro Mikoku

"Fine, fine, I'll go and do it, Izaya-nii. But remember, you still owe me that damned Takoyaki from, like, ten missions ago. Hurry up and get onto that will you?"

- Aojiro's common complaint to Izaya

Aojiro (青白 Aojiro; Lit. Blue and White) is a young teenager who has been classified as a for his association with the ill-reputed Izaya. He is his sole apprentice in the current era, and acts as one of his most trusted spies and confidants despite their age difference. His various acts have lead him to be dubbed, by Izaya himself, as "Wings of the Butterfly" (蝶の羽, Chōnobane), a referral to his oblivious behavior and occupation as a Spy-nin.
