Reze

Reze (レゼ), also known as Lady Reze, is a Bomb Devil hybrid and ally to the Gun Devil. She is the primary antagonist of the titular Bomb Girl arc.

Appearance
Reze is a short young girl with short black hair. She is prone to blushing heavily. On her neck she wears a choker with a grenade pin sticking out of the side.

In her debut appearance she wore a loose shirt with stylized drawing of a bell on the front, and a backpack. While working at the cafe Crossroads she wears an apron.

Personality
Reze initially appears to be a kind and gentle girl who has a crush on Denji soon after meeting him. She laughs at his jokes and isn't afraid to get close to and intimate with him.

She shows little respect towards the owner of the cafe she works at, calling him a cheapskate for docking her pay.

Her true personality is manipulative and brutal, as she is shown killing many Devil Hunters without care or mercy. She does, however, not enjoy killing and prefers to avoid it, unless necessary for her mission.

Bomb Girl arc
As Denji takes cover from the rain by hiding inside of a phonebooth, Reze appears and dahses into the same booth. She greets him and makes comments on the weather before laughing at him and claiming that he reminds her of her dog which has passed away. Denji is initially confused causing Reze to apologize but Denji vomits up a flower he had eaten earlier and presents it to her a trick. Reze thanks him for the flower, blushing heavily, which catches Denji off-guard. Reze lets him know that she works part-time at a cafe called Crossroads and invites him to come by sometime.

Reze wanders over to the cafe and puts on her apron to work and greet her boss. Her boss docks her pay for her lateness and orders her to take a water over to Denji who has already arrived, pleasantly surprising Reze. She sits next to him and orders a coffee for herself and Denji. Denji makes a disgusted face after tasting the coffee causing Rezse to laugh. Her attitude and closeness makes Denji think that she has feelings for him, causing him to worry as he tends to like anyone who likes him back.

Denji keeps coming back to visit Reze at the cafe every day for a full week, ostensibly to order lunch there. Though Denji doesn't want to distrat her from her studying Reze insists on sitting next to him and is shocked when she discovers that he doesn't know how to read. When Denji expresses a wish to have gone to school with Reze, Reze smiles slyly at him and suggests that they both go and visit the school after dark and explore it.

Reze and Denji go to the school and wander the hallways while holding hands. They go to a classroom where they play Reze giving Denji basic lessons. Reze again expresses surprise that Denji never went to school and thinks that it is sad and messed up. She asks him if he is happy with his current occupation killing devils in exchange for the bare minimum standards of living but Denji doesn't have an answer.

At Reze's suggestion the two of them go to the school's swimming pool where Reze strips off and invites Denji in to swim with her. Denji is initially hesitant because he cannot swim and he fears his growing feelings for her but eventually he splashes into the pool and Reze offers to teach him how to swim, and then offers to teach him everything.

After they get out of the pool Reze asks Denji if he'd prefer to be the country mouse or the town mouse, referencing Aesop's fables. Denji opts to pick the town mouse as the food is way better and it seems more fun but Reze thinks that the country mouse sounds better since they'd have freedom. She asks Denji if food and fun are the only things he cares about which he agrees with. Reze invites him to go visit a local festival and after he agrees she runs off to the bathroom, leaving Denji alone in the classroom. As she walks down the hallway Reze turns around a notices a person behind her which she initially mistakes for Denji. The man steps into the light and brandishes a knife at her.

The man chases Reze out onto the school roof. He explains to her that he will use her as bait after maiming her in order to force Denji to surrender and that he'll kill Denji easily once that happens. As he goes to stab her however Reze jumps onto him and easily pivots around to his back, breaking his arm in the process. She puts him into a strangehold and chokes the life from him as she recites a poem in Russian. Once he's dead she stands up and notices the Typhoon Devil's presence nearby. She calsl him as the one responsible for the storm trapping them in the school and accepts the devil's apology so long as he removes the body of his assassin and obeys her for a while. Reze then goes and reunites with Denji in the classroom.

The two of them go to the festival as planned and end up at a cliffside to get a good view of the fireworks. As they wait for the fireworks to go off Reze restarts their earlier conversation about Denji's terrible situation and asks him if he'll quit his job to run away from her, swearing to make him happy and protect him.

Denji questions why she would go so far for him and Reze confesses that she likes him. After hesitating Denji states that he likes her too but due to growing recognition within his job and his feelings towards his coworkers and Makima, he's started to enjoy his life more and more. He asks her if he could keep working as a devil hunter and still see Reze, and Reze responds by saying that Denji must already have someone he likes. She suddenly kisses him on the mouth as the fireworks go off in the background but midway through the kiss Reze bites Denji's tongue off and taunts him with it. She pulls out a knife and cuts his throat, and then cuts his hand off before he can pull his chainsaw cord.

As he collapses to the ground in pain and shock, Reze kisses him again and apologizes before stating that she will take his heart now. Suddenly Beam dashes out of the ground and grabs Denji, taking him away from Reze. Reze scornfully looks down at them and pulls the pin on her choker, causing her head to violently detonate. Her mangled body regenerates into a hybrid state and she rushes after Beam and Denji using the force of an explosion to propel her.
