Ninomiya woke up from his faint and got up from his bed in the infirmary.

I'm at ....... Oh, class.

Class is over."

　When Ninomiya turned around, the infirmary teacher was standing there. Hearing that he had been carried in after losing a mock battle, Ninomiya remembered his fight with Chika.

"Damn, how did I lose?　I was faster than you."

　Ninomiya saw Chika's moves, realized she was slower than him, and thought he could win. However, the result was a perfect defeat. Unconvinced, Ninomiya heads for the dojo of the Yume-Dan style of fighting.

　Although there are dojos of Yumefanryu fighting techniques all over the country, the dojo in Shibusi City was relatively small.

Master, have you ever heard of Nankuru-ryu karate?"

　The dojo's shihan is a lean, well built man named Suzuki.

Nankuru-ryu karate?　Yeah, that's the dojo that's about to go under. I think it's already gone under."

I haven't been crushed. I had a mock fight today with a dojo student there, and we lost."

"You lost," he said. "Tell me the details."

　When Ninomiya tells him that he lost a high-speed battle simulation, Master Suzuki becomes reluctant.

It's just that you are weaker than your opponent. It doesn't mean that the Yumefan style of fighting is weak.

　Then an apprentice named Shibata, who had the physique of a bodybuilder, intervened.

I was like, "What a pity. You lost to such a minor school."

　Ninomiya's mouth twitches.

"You're being too loud. We were dealing with a C-level adventurer.

　Ninomiya is a D-level adventurer, so he looks like he has no choice but to lose to a C-level.

I don't think there's that much of a difference in ability. I don't think there's that much difference in ability.

Anyone can say it.

　Shibata looks miffed.

You're cocky towards your seniors. Watch how you talk."

'You'll have to show me how good you are at it. If you defeat the master of the Nancl style, I'll change my language to respectful and polite."

　Master Suzuki, who was listening to this, raised his eyebrows.

Don't do anything stupid, boys."

　Ninomiya and Shibata replied 'I understand' at the time, but they had no intention of listening to what the master said.

　Wanting to get some physical exercise, I went to the Nankuru-ryu karate dojo. At the dojo, Master Mitsuhashi was teaching Chika and Taichi.

　The teaching methods he used to have a hard time understanding are much easier to understand now that I've pointed them out for him to fix.

"Oh, the Grimms are here, too."

Yes, I came because I wanted to move my body.

I know you're busy, but try to come a little more often. Your body will slow down."

I know, but I've had so much to do that I haven't been able to come."

　After my conversation with Master Mitsuhashi, which was in lieu of a greeting, Chika and Taichi greeted me, and I greeted them back.

　Chika looks at me.

Have you ever been in a simulated high-speed battle, Dr. Grimm?"

If it's a match with those weird weapons, I don't have any experience."

I did a class in college and learned that there are many different types of high-speed combat."

　When Chika commented on the "Raizoku-jutsu" of the Shinsoryu swordsmanship and the "Hien-toujutsu" of the Yumekan-ryu fighting techniques, Master Mitsuhashi listened with amusement.

I suppose those two schools teach you to move quickly with simple movements in the beginning, and then gradually train you to do more complex movements."

I see, so the instructor and Ninomiya-kun were at the beginning stage.

　When I heard Ninomiya's name, I remembered my days at the Magic Academy.

　At that moment, I heard a voice from the gate.

I'll go check it out."

　Taichi heads toward the gate. After a short wait, Ninomiya and an unknown man entered the dojo.

They are dojo-breakers, Master Mitsuhashi. I have never seen them before."

　Taichi said as he looked at Ninomiya and the others with sparkling eyes. Ninomiya glared at Taichi.

Don't look at me like I'm a rare animal, even though I'm your junior."

　Taichi bowed his head.

I'm sorry. I've encountered such a rare thing as a dojo-breaker."

　Ninomiya's companion glares at Taichi with a murderous gaze.

So you're really here to break into the dojo?"

　I ask Ninomiya, and he glances at Chika before answering.

I'm interested in Nankuru-ryu karate, so I came to observe."

　They said they were here to observe, but it was clear that their aim was to break the dojo, as neither of them hid their fighting spirit.

　Ninomiya introduced me to his senior, Shibata, a D-level adventurer who had been studying the Yumekan style of fighting for about eight years. He was about five years older than me. He seemed to be a powerful guy.

　He asked to be allowed to observe, so I sat them down on the edge of the dojo and continued practicing. I repeated basic thrusts and kicks, and then did a promised kumite with Mitsuhashi Shihan.

　Shibata saw this and challenged him.

I knew Nankuru style was nothing," he said. Even our brown belts can beat it.

　I glared at Shibata and he glared back. After that, Shibata repeatedly provoked me, and Master Mitsuhashi's face turned grim.

Master, these two seem to want to be physically active. Why don't you let them participate in the practice?"

'Well, maybe I can join in on the kumite.'

　Master Mitsuhashi seemed to be beginning to think that they were in the way. He wanted them to leave quickly.

He said, "Kumite. You go first."

　Shibata pushed Ninomiya out. Ninomiya came out to the center of the dojo and glared at me.

'Dr. Grimm, because life magic is foul.

I know. I won't use it, don't worry."

　Ninomiya seemed to think he could win then.

　Ninomiya comes out to the center of the dojo, and as soon as he signals to start, he steps in and fires off a quick jab. He brushes off the jab with a right hand and simultaneously fires a low kick to Ninomiya's forward leg.

　The kick, which looked like a foot strike, knocked Ninomiya off balance, but not enough to make him fall, and he stepped back and re-positioned himself. Ninomiya's face was tense. He must have thought he could not let his guard down after my attack.

　I step forward and throw a low kick, and Ninomiya lifts his leg to catch it and throws a right thrust in return. I slam my right arm down on the thrust, and then I spin my right hand upwards and swing it down on Ninomiya's shoulder.

　The pain creates an opening, and Ninomiya is hit in the stomach with a kick to the knee. Ninomiya collapses from the blow.

That's it.

　Master Mitsuhashi stopped him. Shibata, who was watching, bit his lip.

Next, Mr. Shibata, will you take me on?"

　I said, and Shibata shook his head.

No, I want Master Mitsuhashi to play with me."

　I thought he was very confident. Did he think I wasn't good enough?　Well, I am sure that Master Mitsuhashi will not lose.

　I went and sat down beside Chika. Instead, Master Mitsuhashi advanced to the center.

　The true value of the Yumekan style of fighting techniques was not understood by Ninomiya. Let's learn it from Shibata. Master Mitsuhashi and Shibata faced each other, and a match called kumite began at the sound of the master's voice.

　Shibata barked, eyes lifted, and suddenly tried to step in and deliver a front kick. Master Mitsuhashi had completely foreseen this attack. He stepped forward in the preliminary movement stage, known as the "omiki" of the technique, played the kick with his left arm, and simultaneously fired a right thrust at Shibata's dove tail.

　He thought Shibata was going to pay him with his arms, but he couldn't seem to react. It must have been the first time he had received such a technique. Mitsuhashi Shihan's mid-level thrust was cleanly smashed into the opponent's stomach.

　Chika tilted her head when she saw Ninomiya's senior, who had been killed instantly.

Why did this man appoint a master teacher?"

　For all his big talk, he was not accompanied by any real ability. As expected of Ninomiya's senior, I thought.
