Seitarou Senpai and Training

3rd POV:

You enter the room and see a chair in front of several monitors. On the seat in front of it sits a person with long blue spiky hair. It reminds you of the warden, except it's lighter. "[L/N], this is Tanabata Seitarou." Hajime introduces, pointing towards the person. They spin around in their chair at their supervisor's voice, and you are met with two pink eyes. "H-Huh? Oh, the new guard!" he says as he scrambles to his feet. 'Cute.' you think at his clumsy and shy behaviour.

"My name is Tanabata Seitarou, a building 13 guard, pleasure to meet you." he says curtly. "My name is [Y/N], Jr. guard at building 13. Nice to meet you, Tanabata-senpai." you say, followed by a curt bow. "S-Senpai?" Tanabata stutters. "That's right Seitarou, you're a senpai now. Show the newbie the ropes." Hajime grins, patting Seitarou on the shoulder. Seitarou beams, excited by the situation. "Ahem, I'll show you around the building, [L/N]-kouhai." (Kouhai is opposite of senpai, senpai is someone of a higher or more experienced position.) Seitarou declares, leading you out of the monitoring room. You're shown the cafeteria and the break room by a beaming Seitarou, who is nervous but also very excited to have a kouhai.

"Hahahaa! Hello Tanabata, what a good day to excersise, am I right?" a deep voice calls out behind you both. You turn around and see a tall man jogging your direction. He has dark grey eyes, thick eyebrows and long, black hair worn with only the bangs loose, reaching past his chest. "Yamato! Oh, [L/N], this is Godai Yamato, the deputy supervisor of the building." Seitarou introduces. "My name is [Y/N], a new jr guard here at building 13. Pleasure to meet you Godai." you say, adressing him by his surname with a bow. "No need for the formalities. Would you like to join me on a jog?" he says, his voice still deep yet filled with goofiness. "I'm sorry, but I am still getting familiar with the building. Maybe another time." you reply, to which he utters a 'It's fine.' and continues jogging.

Seitarou then continues guiding you about, teaching you how to navigate the building. "And then you'll turn left and reach my office." he says as you walk along a hallway. "But how do I get to the metro?" a familiar voice pipes up. "Oh, you'll have to-" Seitarou starts, but you interrupt him by stopping and turning around. There's Jyugo behind you, and his hands rise in fake surrender. "Don't whack me this time!" he says, mild panic in his voice. "Why shouldn't I, number 15? You should be in your cell right now." you say, giving him a mild glare. "Number 15, you need to go back to your cell!" Seitarou says, huffing at Jyugo.

"Eh, I'll pass." Jyugo shrugs. At this you look from Jyugo to Seitarou and back, which flusters the guard. He won't be embarassed in front of his kouhai! "Number 15, cell, NOW!" Seitarou yells, surprising Jyugo a little. "What are you playing at?" Jyugo asks, arching an eyebrow. You're standing behind Seitarou now that he stepped forward, so you pull out your baton. Jyugo's eyes widen, and he raises his hands. "Fine, fine! I'm going." he says and starts to leave, but is yanked back as he feels a handcuff around his left hand.

"Now now, what kind of guards would we be if we wouldn't escort you? We wouldn't want you to wander somewhere else, now would we?" you say, giving him a close eyed smile. Jyugo looks at you again, each time he does that it feels like he's analyzing you. You gotta admit, his eyes are very pretty. They change color at various angles and shimmer in the light (In the manga his eyes change colors at various angles. In the anime he's just heterochromatic (eyes don't share color)).

You and Seitarou put him back in, getting curious glances from Uno, Rock and 25(Nico, the protag just doesn't know his name yet). Suddenly, the inmates dash against the cell door and let out a yell once hitting it, scaring poor Seitarou. You just furrow your brows and hit the closest head with your baton. "Ow!" Uno yells, clutching his head. "Don't do that again." you growl as they back off from the door as not to get hit as well.

As you walk away from the building and towards the metro, your mind runs wild with ideas how to train the inmates to behave. Still, there's something else you should focus on - training. You have been assigned to train with the building 5 supervisor, Samon Gokuu. You sweat as you enter a large courtyard and see a person stand there. He turns around and you get a good look.

He's a shorter man, sporting orange hair that ends in green bangs. He has green eyes outlined with red makeup, added by red makup dots at the corners of his mouth. His hands are covered in white gloves like almost all guards wear, but what stands out is what is attached to his belt - a red ornamet that looks like a monkey tail. It's red, but white at the end, As he spots you he grins and beckons you, then his tail flicks as he moves. You are stunned by the fact that the tail moves as if he was a living monkey, but then snap out of it and head for him. "Supervisor Gokuu, nice to meet you. My n-" you start to say, but he cuts you off "[L/N], right? I recognized you by the building 13 armband.". "Yes sir." you simply grin back. "Alright, let's begin with assesement." he says, raising his hands for combat.

Three seconds later you're laying face down in the dirt. "Alright, first you need to improve your stamina and strenght, I can see you need more to land a proper punch." he says as you get up and dust off yourself. "Fifty pushups." he says. Once his command registers in your head, you get down on the ground and start. By the time you reach fifty, you're exhausted. "You're weak and slow... but you got dedication. Good work." he says, giving you a thumbs up. "Thank you, sir." you say with heavy breathing, then scurry off.

That evening you make a few calls and fill some papers, then recieve three packages. You will use these tomorrow...
