Boze is a one-shot written and illustrated by Ryōji Hirano. It was published in Weekly Shonen Jump on March 28th, 2016.
Urado Shiori, a first year in high school, is saved by a mysterious monk named Ryudaiji. However, Ryudaiji is not your normal monk. He uses modern weapons combined with spells in order to exorcise demons that are terrorising the world. With his Gatling gun and two automated stone lions A-Gon and U-Gon, he saves Shiori from a vampire.
Urado Shiori is being held against a wall by a Vampire, who is planning on killing her. Shiori wonders if she is going to die and has a "lame" flashback. However, a Monk named Ryudaiji intervenes, who calls it a "sort of fate". The Vampire claims that he's always wanted to see a Monk (which he refers to the "Exorcists of Japan") for himself, and taunts Ryudaiji, asking him if he's going to start praying.
Ryudaiji says that his taunts are tiresome, and proceeds to attack the Vampire with a Gatling Gun, thus saving Shiori from death. After the Vampire claims he will have revenge, A-Gon and U-Gon appear, apologising to Ryudaiji for being late and asking him if he is okay. Ryudaiji says that he is fine, and informs them that they will return to base after he has cleaned up the mess. A-Gon and U-Gon wonder if they should protect Shiori, and Shiori passes out.
Shiori is woken up at school by her friends. Her friends wonder what she means by "Monk-san", "Gatling Gun" and "The Villain Passing By", and ask her what kind of dream she had. They then ask if she is ready for the test, much to her surprise. However, this is instantly forgotten when one of Shiori's friends gets a papercut on her finger. Her other friends offers her a band-aid, but doesn't manage to put it on before Shiori bites her fingers.
Shiori wakes up flying in the air with Ryudaiji, who asks if his fingers taste good to Shiori. She takes his fingers out of her mouth with embarrassment and apologises to Ryudaiji. She realises that she isn't in a dream, but doesn't consider it as real. Whilst stopping to buy something from a vending machine, Ryudaiji introduces himself to Shiori and states that she must be quite confused with what happened previously, calling her "finger-licking vomit girl". Shiori again feels embarrassed and thinks that her first impression is terrible. Despite her embarrassment, Shiori introduces herself, and tells Ryudaiji that she is a first year high school student. She then thanks Ryudaiji for saving her, but says that she will go back home. However, before is able to leave, Ryudaiji tells her that there's a doctor at where he stays and that she can go back home afterwards.
Shiori, Ryudaiji, A-Gon and U-Gon arrive at the temple. A-Gon and U-Gon say goodnight to Ryudaiji and leave his side. Shiori gets distracted by a shrine, but is then beckoned by Ryudaiji to follow him into the temple. After entering, Ryudaiji warns Shiori to maintain her footing for the descent. To Shiori's surprise, the lift drops quickly. Once they reach the bottom, Shiori is amazed by the underground headquarter that has been set up underneath the temple, but wonders why it is where it is.
Shiori is then greeted by Yaobikuni, who is scolded by Ryudaiji. Ryudaiji then confirms that Yaobikuni is his great (x9) grandmother, which surprises Shiori. Yaobikuni informs Shiori that she was taken to have some experiments on her body a long time ago, which made her immortal, to which Shiori chides her for not telling her sooner. Yaobikuni proceeds to claim she is quite pleased that Ryudaiji has brought "his girlfriend" home with him, to which Shiori denies.
Yaobikuni informs Shiori of the Hazama (the demons of the inbetween) while the latter is being injected. Ryudaiji interjects, saying that what attacked Shiori is referred to as a "vampire". Shiori replies that they sound like foreign monsters.
