Chapter 18: 3.1

「Then! Please take care of me from now on, teacher! Osu*!」

TN: It’s a polite way of saying yes or please. If you read karateka mangas, you should be familiar with it.

Yui, dressed in a tattered, worn-out karate outfit that I don’t know where she got, bowed.

Sleeveless, worn out, and tattered. From the sides, you could catch a glimpse of her big boobies.

Furthermore, the lower body was shredded above the knees revealing her trademark black tights.

It seems like even if she’s wearing that, she doesn’t slip on the wooden floor.

As expected of a divine object.

Though the divine object might not be happy of being admired as an anti-slip thing.

We are currently at the Shiratori family dojo.

Yui, who saw my battle last night, asked me to train with her.

I mean, do they even have their own private dojo?

At first glance, it looks like an ordinary dojo but the walls and floors are made of reinforced materials.

「Even if you say special training….if you train your body well and pass through the line of death many times, you can become stronger on your own.」

「That advice is not even close to being helpful….how do you train your body? I train with everything I have at the gym.」

Indeed. She had supple and lean muscles.

「Hmm, you’re no better than a top class athlete.」

「You’re saying it like it’s bad!?」

「If you don’t have muscle quality beyond of that a human, your body won’t be able to keep up with your own attacks.」

「Beyond of that a human……big muscles will only slow you down. Even that alien who turns blonde said that.」

「You’re familiar with shonen manga too.」

「I read a lot of manga to see if I can get any insights of how to do it.」

「Don’t rely on manga for insights.」

But on the other hand, I also used my manga and anime knowledge to find how to do things in the other world.

However, I’m already powerful and only used manga and anime as reference back then.

「The problem is not quantity but quality. Would you like to give it a try?」

「Try what?」

「Muscle training.」

「Hnfufufu. I have confidence in muscle training.」

—30 minutes later—

「Haa…..haa….please forgive me already….afu…..」

Yui’s cowering on the floor while trembling.

I gave her a little lightened version of the muscle training I did on the dark side of the moon.

Let’s finish this with a heal.

I put my hand on Yui’s body and a warm light enveloped her body.

「Ugh….healing magic feels very pleasant but the reconstruction of muscle fibers is too painful….it can also be said to be traumatizing…」

「If you do this for 24hrs a day for a week or so, you’ll instantly have a body that can make you escape from a demon.」

「I’m going to die first!? I mean, the demons are amazing. I’m glad we don’t have them in this world.」

I once gave this muscle training to all the young people in the village when I rescued a villager who was targeted by a demon. It was a hellish scene full of scream.

One of the members of my party when I defeated the demon king came from that village.

「Even in the manga that Yui was saying, the main characters will become stronger once they come back from the brink of death, right? It’s similar to that.」

「Don’t try to convince me using a manga!?」

Okay, calm down.

「Then, let’s have muscle training little by little, day by day. For now, I want to see Yui’s ability. Then….」

I chanted a little and a magic circle appeared on the floor. From that magic circle, a dark valkyrie like the ones we fought last night appeared.

「How can you summon a dark valkyrie!? No way….you’re a greater variant that transformed into Kazu!?」

Yui, who took a big leap, braced herself against the dark valkyrie.
