In a crossover anime, the only way to become stronger is by marrying a wife.

"..."

Hiratsuka Shizuka glanced at Tsukikawa Shuu, then at Goto Ichiri, feeling inexplicably uneasy.

She didn't know what was going on.

In short... I'm Tsukikawa Shu's teacher, so I'd say I'm practically his mother... We used to have a pretty good relationship, but seeing him with someone else now makes me a little uncomfortable...

“Ichiri, there’s actually one more thing I need your permission for.” Tsukikawa Shuu looked at Goto Ichiri, and when she looked into her eyes, her expression suddenly became very serious.

Tsukikawa Shuu no longer intended to conceal the system's mission settings, but Goto Ichiri's opinion should still be considered in this matter.

"I want to have a harem!"

Tsukikawa Shuu said it very bluntly.

Chapter 21

"Huh?" Goto Ichiri was a little confused.

Hiratsuka Shizuya gradually opened her eyes wider.

Although I've read many time-travel novels, where harem elements are common, it's still not something that can be accepted in today's society...

"My strength can only be unleashed through this method," Tsukikawa Shuu explained directly to Goto Ichiri.

She made all the requirements of her own system clear to Goto Ichiri.

"I don't know how many dangers still exist in this other world. Although we are able to survive now, we don't know if we will be able to survive smoothly in the future."

Tsukikawa Shuu said, "Next, we will face more advanced animals, and we may even have conflicts with other players. Later on, we may even have to fight against groups of multiple players."

"Strengthening my strength is essential, and I will not let go of any opportunity to do so."

"And this is the main way I become stronger: every time I form a contract with someone, I receive a lot of rewards and preferential treatment from the system."

"Perhaps there are other ways to become stronger, but I don't want to be controlled by others or unable to protect those around me in the future because I'm not strong enough."

Goto Ichiri listened quietly to Tsukikawa Shuu's words, and took his hand. The two looked at each other and waited for him to finish speaking.

"So, I want to become stronger, and I want to protect the people I care about."

"But I'd also like to hear your opinion."

Tsukikawa Shuu took a deep breath and tightened her grip on Goto Ichiri's hand slightly.

"I will not give up this special advantage I have."

"And we haven't done the things that a married couple should do yet. If you don't agree, I won't touch you again, and I won't ruin your life."

"Although the contract of fate is difficult to break, I will try to find a way to break it."

Hiratsuka Shizuya listened quietly to Tsukikawa Shuu's words, staring intently at the two of them, glancing between Tsukikawa Shuu and Goto Ichiri, trying to see what changes the other would make.

Although I usually serve as Hiratsuka Shizuka's teacher, I know that Tsukikawa Shu is always straightforward and the type who speaks his mind and will even take action if he is upset. But I never expected him to be so blunt about this kind of thing.

If you keep it a secret and sign a contract with someone else, given Goto Ichiri's clueless nature, it'll probably take her a long time to find out. By then, it'll be too late; you can just make up some excuse, and she probably won't be able to do anything about it. Hiratsuka Shizuka thought to herself.

However, Tsukikawa Shuu still brought it up directly.

He's a scumbag, but not a complete scumbag; he hasn't even slept with her yet.

Although Hiratsuka Shizuka is quite interested in gossip, today's gossip was far beyond her expectations.

“Ugh…” Goto Ichiri’s expression didn’t change much, but he lowered his head slightly and tightened his grip on Tsukikawa Shu’s hand.

She thought about it for a while, and finally laughed.

"There's nothing we can do about it; we have to survive."

Goto Ichiri paused for a moment, then continued, "And it was you who saved me. Without you, I probably wouldn't have been able to team up with anyone, and even if I did, I would have been quickly abandoned... I would have been doomed anyway."

Goto Ichiri was also surprised when Tsukikawa Shu confessed this to her directly.

But then I thought, this is the inner world, and all the rules are set by this system. Burning, killing, and looting are commonplace, and having a harem seems quite normal... After all, strength is king, and that is the ironclad rule of this world.

If he hadn't met Tsukikawa Shu, with his foolish appearance and terrible athletic ability, even if he had managed to hide and survive the first time, he would have been doomed to die this time when he entered the underworld. He wouldn't have been able to face those terrifying monsters at all, and would have become experience points for others to hunt down.

And then... Tsukikawa Shuu got stronger and benefited more, and I also got stronger thanks to this system setting of hers, so I was basically clinging to her coattails.

Furthermore, the contract of fate is not just a piece of paper; both parties must treat each other well, so you don't need to worry about being bullied or anything like that...

Before he knew it, Little Boqi had won himself over.

"So, you agree?" Tsukikawa Shuu gently kneaded Goto Ichiri's small hand.

"Hmm." Goto Ichiri thought for a moment, then nodded emphatically.

After all, the rules of the other world cannot be measured by the values ​​of the world one lives in.

"it is good!"

Tsukikawa Shuu was overjoyed and pulled Goto Ichiri into her arms with a strong pull.

"Whoa!"

Caught off guard, Goto Ichiri found herself already lying in Tsukikawa Hiiragi's arms when she came to her senses.

Even with the increase in level and physique, Goto Ichiri's characteristic of being oblivious and having a long reflex arc remains unchanged.

"But it's a promise... you have to take responsibility for me."

Goto Ichiri said somewhat timidly.

Tsukikawa Hiiragi smiled.

Even if Goto Ichiri hadn't said anything, Tsukikawa Shu wouldn't have given up on anyone willing to entrust their fate to him.

"You two... are you just going to do this?"

Hiratsuka Shizuka stared blankly at the two of them, still unable to switch her worldview from her original one. "Besides, is it really okay for me, an outsider, to listen to what you're saying?"

"Um……"

Tsukikawa Shu thought for a moment, then said, "Actually, I also quite like Hiratsuka-sensei..."

Before he could finish speaking, he was hit on the head with a paper tube.

Hiratsuka Shizuka rolled up a newspaper and tapped Tsukikawa Shu on the head.

"You even dare to think about me, your teacher?" Hiratsuka Shizuka said, somewhat annoyed. "And don't you even consider how different we are?"

"With a teacher this beautiful, which boy wouldn't be attracted to her? It's just that I dare to say it, but others don't."

Tsukikawa Shu touched the spot where she had been hit. "Besides, Hiratsuka-sensei has always refused to tell us her real age."

"..."

When Tsukikawa Shu praised her beauty, Hiratsuka Shizuka wanted to get angry, but found that she wasn't angry at all.

Looking at Tsukikawa Shu's gentle and kind face, I actually felt a little happy instead.

It's true that being handsome allows you to do whatever you want.

"Fine, given the current situation, I won't pursue your disrespectful behavior towards your teacher," Hiratsuka Shizuka said.

"I see that Goto's level is rising quite fast, it seems to be about the same as yours. Do you have any skills or talents that you could share with me?"

“This is also a result of the marriage contract,” Tsukikawa Shuu said.

"The marriage contract can increase experience by double, and both parties can obtain the full experience of the monster after it is killed."

"Huh? You need to get married to unlock this?" Hiratsuka Shizuka was stunned.

Chapter 22 The Night Is Still Long

"Are there any other ways besides signing a contract?" Hiratsuka Shizuka then asked.

Although she knows martial arts, in this alternate world, her skills only slightly increase her chances of survival. To truly become stronger, she must follow the rules of this world.

"If you're lucky enough to find experience-boosting cards while exploring, leveling up will be quite fast," Tsukikawa Shuu said.

"I do have some experience point cards here." Tsukikawa Shuu opened his backpack.

However, several large characters were clearly written on it.

[Experience cards can only be used by the user and the person who signed the contract.]

This setting is similar to how support characters in games can only be used by friends, and only friends can gift characters to each other.

However, in this alternate world, the friend has been replaced by the contract signer.

"..."

Hiratsuka Shizuka read through the system instructions, but for a moment she didn't know what to do.

Tomorrow, Tsukikawa Shu will set off to farm materials and experience in the dungeon in the eastern suburbs of the city. However, the further away from the city center the dungeon is, the greater the danger becomes. Hiratsuka Shizuka definitely cannot go with her; she would only be a hindrance.

"I will try my best to help you, teacher," Tsukikawa Shuu said. "When hunting monsters, the last hit gives more experience points, so I will help you control the prey."

"How much time does this take?" Hiratsuka Shizuka asked after thinking for a moment.

She had never hunted monsters in this alternate world before, and still had no concept of experience points.

"Wait a moment." Tsukikawa Shuuya thought for a moment, then left the room.
