Mairimashita! Iruma-kun Wiki

Barbatos Bachiko is one of the prestigious professors at Babyls Academy, a school in the demon world and a candidate for the seat on 13 Crowns, heroes of the demon world.[1]


Bachiko is shorter than Iruma Suzuki. She has long, twin-tailed magenta hair and wears a shortsleeved frilled dress with striped stockings and bow-tied shoes. She is often depicted with jailbar teeth and she always has a toothpick hanging out of her mouth.


Initially, Bachiko comes off as a stereotypical delinquent brat: Loud, short-tempered, selfish, and tomboyish. This attitude is later revealed to have developed as a result of her frustration, after the countless demons she attempted to teach her skills to ultimately all gave up because they lacked the patience to master archery. However, she also is shown to recognize and respect when a person is truly committed to learning the skills she endeavors to pass on to them, as proves to be the case with Iruma.



Barbatos Family - Full Marks (One Hundred Shots, One Hundred Hits), Bachiko's bloodline magic. It enables her to manifest a bow, and fire up to 100 magic arrows simultaneously which will always strike their target without fail, regardless of distance or interference. Even among demons, her ability is rare for two reasons: One, she is one of only three people in the Barbatos family who can fire 100 arrows in one go using the ability. Two, archery is nearly impossible for demons outside the Barbatos family to master, due to them lacking the patience to maintain the concentration needed to shoot an arrow.


Iruma Suzuki - The student Bachiko was asked to aid in tutoring by Lord Sullivan. At first, she openly tells him he's an idiot for going along with the ridiculous demands and chores she heaps on him at the beginning of her "training" him. However, after beginning to train him in earnest by passing on her archery skills to him, she recognizes his dedication to learning from her and treats him with a bit more respect. Upon learning that he is a human from Sullivan, she is momentarily shocked and panics, but ultimately her resolve to continue teaching Iruma is only strengthened by learning what he is, as she decides he is the only person who could be her student precisely because he's not a demon (in light of her past failures in trying to teach actual demons how to be archers).

Bars Robin - Relative. Member of the Branch Family. Like many of his peers, Bachiko recognizes that Robin is quite naive and dense when it comes to teaching.

Sullivan - Bachiko greatly respects and admires Lord Sullivan, to the point of becoming somewhat flustered in his presence. She is also extremely loyal to him, being willing to set off and attack the Six Fingers with her bloodline ability if she thinks he wishes her to do so. Sullivan, in turn, also appears to trust her greatly, as he was willing to reveal to her that Iruma is a human after the Harvest Festival.
