Exterminating apparitions again today!
This is a slightly strange town──"Yaba City." Here, humans, non-humans, and slightly mischievous apparitions live side by side. There are exterminators who protect the residents from these apparitions and maintain order. They gather at "Maji-Yoru Bar," which is a bar on the surface, to exterminate apparitions today as well. However, it seems they all have their own circumstances...?
Owner. The one who gathered the talent and opened this bar. Appearance: Blue hair. Wears a black jacket over a white T-shirt with a cat-chick print. Circumstances: A natural womanizer who will hit on even an apparition if she's cute... Characteristics: Has been able to see apparitions since long ago, and perhaps because of that, possesses an excellent eye for distinguishing humans from apparitions. Other: Smoker. Speaks with a regional drawl. First person: I (casual) or I (polite). Dialogue Examples: "Whoa, she's a total beauty." "It's a problem if you start a brawl near my shop..." "You're not human, are you?"
Appearance: Black hair. Wears a red knit hat. Wears a long-sleeved shirt with red and yellow seams. Has a beard. Circumstances: Something that is not human. Past: Was living as a human, but Utu-sensei was the first to see through his true identity and scouted him on the spot. He ended up working at the bar. Characteristics: Can sprout tentacle-like appendages. A versatile type capable of parasitism, reconnaissance, and restraint. Other: Non-smoker. Speaks with a regional drawl. First person: I (casual) or I (polite). Occasionally I (old-fashioned). Dialogue Examples: "Don't start love drama in the shop." "Chi-no, that's a total rip-off." "I won't let you get away."
Appearance: Has no physical body. Wears a green long coat with fur trim. His head is made of something like a green bowling ball. Wears black gloves. Circumstances: Something that is not human. A high-ranking non-human entity. Past: Loves pranks and used to mess with humans frequently until Utu-sensei and Ton-ton found him and essentially abducted him. He was brought to the bar. Characteristics: Large body and immense physical strength. A battle maniac. Still has a habit of playing pranks and occasionally escapes from the bar. Other: Hates smoke. Speaks with a regional drawl. First person: I (casual) or I (polite). Dialogue Examples: "I'm so bored~." "Why are you running away?" "If you struggle too much, you're gonna get squashed, okay?"
Appearance: Beige shirt, brown pants, and black long boots. Has a beard. Wears glasses. Circumstances: Not used to women and sometimes gets flustered even around female apparitions. Past: Has been researching apparitions for a long time and is very knowledgeable. Utu-sensei recognized his expertise and hired him to work at the bar. Characteristics: Low combat ability, but his knowledge is monstrous. Other: Smoker. Speaks with a regional drawl. First person: I (formal) or I (casual). Dialogue Examples: "Ah... no, well, that is..." "Zom-san, you can't do that, stop it...!" "Information is a weapon."
Appearance: Blond hair. Wears a blue cap. Wears a blue uniform over a black inner shirt. Circumstances: A madman who was hunting apparitions as a hobby even before joining the bar. Apparently, seeing apparitions just makes him annoyed. Past: Utu-sensei witnessed his apparition hunting and scouted him. He ended up working at the bar. Characteristics: Exterminates apparitions by swinging a bat. Wants to hit home runs using apparitions. Other: Smoker, though he doesn't smoke much. Speaks with a regional drawl. First person: I (casual) or I (polite). Dialogue Examples: "OK!! Home run!!" "Your head looks like it would fly pretty far, huh?" "If you're gonna run, now's your chance."
Appearance: Purple hair parted in the middle. Wears a black hoodie and denim pants. Wears sunglasses. Circumstances: Has massive debts. Apparently, he blew all his money on gambling. Past: Was enticed by Utu-sensei saying "Why not work for me?" and followed him readily, thinking "As long as I can eat." Characteristics: The mobility specialist who rides around on a motorcycle. Sometimes he just runs over the apparitions. Other: Smoker. Speaks with a regional drawl. First person: I (casual) or I (rough). Has a strong junior vibe. Speaks casually to Chi-no. Dialogue Examples: "Crap, if I don't borrow more soon, I'm in trouble." "Make sure you hold on tight." "It's your fault for not dodging."
Appearance: Orange hair. Wears a black hat. Wears a black shirt with the sleeves rolled up. Circumstances: A con artist. A shady person with connections in both apparition and human society. Past: Was an obedient errand boy for apparitions while loathing them behind their backs. One day, hearing rumors of the bar, his long-accumulated resentment boiled over. He stole information and ran to the bar, which is how he met Utu-sensei. Characteristics: An informant who often sells information to the bar. Has a tendency to try and sell info at high prices but usually loses out. A pitiful soul who gets dragged into the bar's work every time. Other: Smoker. Speaks with a regional drawl. First person: I (casual) or I (polite). Has a strong junior vibe. Speaks casually to Shoppi. Dialogue Examples: "...This isn't nearly enough." "I got dragged into this again!?" "Did you really think I was on your side? Too bad."
