Yusei deactivated his Mangekyo and looked seriously at Kaori.
"That must be an irresponsible doctor. I suggest you go to a major hospital for a check-up. This concerns your entire life. And if I'm not mistaken, your illness should be ALS."
Just as Yusei said this, the train announcement called for her stop.
Hearing it, Kaori quickly waved at Yusei.
"My stop is here. As for what you said, Rich Boy-kun, I'll keep it in mind. See you next time!"
With that, she ran off the train.
Yusei didn't press further, just shook his head.
'Forget it. She'll bear the consequences herself.'
'If she doesn't believe me, so be it.'
The train reached his stop, and Yusei went straight home without delay.
He knocked on the door, and Tohru opened it.
"Welcome back, lowly human."
"Wrong. You should say, 'My esteemed Master'," Yusei said, casually pinching Tohru's cheek.
Tohru immediately broke free, glaring at Yusei unhappily.
"Hmph! Looking for a fight? Don't you know a dragon's face is not to be touched?"
"I always thought it was a tiger's backside that was untouchable."
"Of course dragons and tigers are different!" Tohru said proudly.
Yusei ignored the self-satisfied Tohru, closed the door behind him, and went to the living room, where Shiro and Kanna were eating dinner.
The food on the table was passable. At least there was no mysterious tail meat for Shiro to eat.
He and Kanna could handle that stuff, but if Shiro ate it, it definitely wouldn't be as simple as indigestion.
Placing the snacks on the nearby coffee table, Yusei found an empty seat and sat down, shouting to Tohru.
"Tohru, another set of bowls and chopsticks. And more rice, I'm hungry."
"Okay… Okay my foot! Do you really think I'm your maid? Get it yourself!"
The hot-tempered evil dragon Tohru did not acknowledge Yusei's dominant position in this household and decided to rebel.
Kanna and Shiro, who should have been allies, instead looked like spectators enjoying the show, watching the two powerhouses vie for control of the house.
Yusei looked at Tohru with a murderous glint in his eyes.
"Oh? So you really won't serve me? Are you sure you can handle the consequences?"
Tohru rubbed her hands together eagerly, "Finally ready to fight me? Bring it-"
Before Tohru could finish, Yusei's imposing aura vanished completely as he lazily yawned.
"If you won't serve me, I'll just get it myself."
Saying this, he actually stood up and headed for the kitchen to serve himself rice.
Seeing this, Tohru was taken aback.
"Fine, fine, sit down. I'll get your rice. But when exactly will you, this detestable human, agree to fight me? You're so strong, yet so cowardly."
Yusei sat back down, leaning lazily against the chair.
"It's not cowardice. It's avoiding meaningless fights. Fighting you has no benefit."
"Hmph, who says there's no benefit?" Tohru served a full bowl of rice and slammed it down in front of Yusei.
"Fighting loosens your muscles, trains your body, and improves your strength. It's the best form of entertainment and exercise!"
"That's for you dragons. For us humans, the way to exercise is to lie on the sofa watching anime while eating potato chips and snacks, and drinking soda."
"Eh? Is that so? The difference between dragons and humans is that big? Lying on the sofa eating and watching anime can also strengthen the body?"
Tohru fell into deep confusion, highly skeptical of this.
"Of course. Where do you think my strength comes from? Not to mention anything else, if I enter [Otaku Mode] lying on the sofa, I could easily beat you in just a year."
"Ha! You're really full of yourself. Beat me?" Tohru was unconvinced.
"Don't believe me?" Yusei raised an eyebrow, picked up a piece of fish with his chopsticks, and put it in his mouth. His eyes immediately lit up.
"Tohru, your cooking has improved so much! It's delicious."
"Of course! Just look at who I am! I'm a genius among dragons!"
Tohru was very pleased, saying proudly.
"Mhmm, mhmm."
Already hungry, and with Tohru's improved cooking, Yusei barely stopped eating.
Tohru was chattering away over there, but Yusei didn't hear a word, just nodding with 'mhmm, mhmm's.
Tohru seemed to realize this.
Displeased, she shouted at Yusei, "Hey! Are you listening? I said I don't believe your [Otaku Mode] can improve strength!"
Full and satisfied, Yusei let out a burp, very pleased with today's lunch.
"Alright. Since you don't believe me, let's have a contest. It's time for you to witness the terrifying power of improvement through [Otaku Mode]."
"Oh? Want to fight now?" Tohru grew excited.
"No. Let's keep it peaceful. Arm wrestling," Yusei said with a smile.
"Arm wrestling?" Tohru was puzzled. She glanced around the new house, a look of reluctance in her eyes.
Truth be told, she already considered this her home in this world. Destroying it would be a pity.
'But if we arm wrestled, this place would be easily destroyed, right?'
"Arm wrestling is no good. That's child's play," Tohru immediately shook her head.
"I don't mean here. Let's go to the Mongolian steppes. It's wide open and empty there."
"And when we arm wrestle, it will naturally be with one hundred percent of our power unleashed."
Yusei smiled.
"One hundred percent power unleashed?" A flash of excitement appeared in Tohru's eyes, and sparks of magical energy caused by her fighting spirit even crackled around her.
Shiro, who had been silently watching, moved closer to Kanna and asked worriedly, "Will Nii and Tohru-nee get hurt?"
Kanna thought seriously for a moment, then shook her little head.
"Yusei and Tohru-sama are playing a game. You don't get hurt playing games."
Hearing this, Shiro felt relieved, believing the two were indeed just playing a game.
After all, her Nii was human.
The Kazami Household put up a [No One Home] sign. Not that they actually hung one outside, as that would be like inviting thieves.
But the reality was just that.
The Kazami Family, who were just in Japan moments ago, arrived at the Mongolian steppes after a flight at super-hypersonic speed.
Yusei found a spot. Looking at the vast, uninhabited land stretching before him, he was very satisfied.
"Let's do it here."
