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

She hadn't expected Tsukikawa Shu to be so direct.

"This one……"

Mahiro Oyama did not answer immediately, but instead lowered his head.

Tsukikawa Shuu wasn't in a hurry; he simply held the girl and sat quietly.

"It's not impossible."

After a long pause, Masato Oyama finally spoke.

"Ah."

Tsukikawa Shu smiled and said, "Alright, let's be together then."

"But you have other girls around you, right?" she asked. "Sometimes at night, I can hear noises coming from your side."

"They heard us."

Tsukikawa Shuu scratched his face, then readily admitted, "Indeed, I have several boyfriends now."

"So, Tsukikawa-kun is a scumbag?" Mahiro Oyama looked up at Tsukikawa Shuu.

She could understand the boy's feelings, after all, she had experienced it herself, and when looking at various visual novels, most of them ended up with a harem ending.

However, now that it's my turn, thinking like this still feels a bit unnatural.

Even if I agree, what about the others?

“There’s a reason for that,” Tsukikawa Shuu said.

Chapter 244 Kiss

"I don't know if you've ever heard of anything about the 'other world'."

Tsukikawa Shuu said, "This is a world that belongs to a completely different space than ours."

Oyama Shinsuke thought for a moment, then nodded.

"I think I have seen it before. It seems to be a game. There are many people sharing their experiences and stories on the forum," said Masahiro Oyama.

The existence of the afterlife has now become a kind of urban legend on the internet.

"Have you ever considered that this world actually exists?"

Tsukigawa Hiiragi said.

"Does it really exist?" Mahiro Oyama asked, somewhat puzzled.

"Yes, it really exists, and I need your help too."

Then, Tsukikawa Shu looked into the other person's eyes and said very seriously, "This is a very serious issue that will affect your entire life, so I will tell you the whole process and all the details, and you can make your own judgment."

Tsukikawa Shuu opened her palm, and a bright flame ignited in it.

"Huh?" Mahiro Oyama blinked, looking at the flame. "Is this magic?"

"No, it's real, a skill just like the ones in novels and games."

As Tsukikawa Shuu spoke, she retracted her hand and then waved it lightly twice in the air.

A silvery light suddenly appeared all around.

A dozen or so sharp swords appeared around them, their blades reflecting a cold, gleaming light.

Masahiro Oyama was stunned.

This has completely gone beyond the realm of magic.

"Here's the thing: the underworld also really exists."

Afterwards, Tsukikawa Shuu explained the situation regarding the Otherworld to Oyama Mahiro.

This also includes the important concept of a marriage contract, as well as the current predicament he faces.

"So, in order to deal with the next calamity boss that will be born in the underworld, Tsukikawa-kun also needs to get married to become stronger?" Oyama Mahiro asked.

“That’s exactly what I’m planning to do; it’s the fastest way.” Tsukikawa Shu nodded, then added, “Of course, you can refuse if you don’t want to.”

“Actually, I already believed in Tsukikawa-kun after he proved the existence of the Otherworld.” Oyama Mahiro laughed. “Well, since it’s for the greater good, Tsukikawa-kun had no choice but to do it this way.”

"So, can you promise me and sign the contract?" Tsukikawa Shu grasped her hand.

“If it can help Tsukikawa-kun—” Mahiro Oyama nodded emphatically, “I agree!”

"Thank you."

Tsukikawa Hiiragi laughed.

Then he stood up, "However, this still needs the family's consent."

“I’m an adult, after all!” Mahiro Oyama pouted, then muttered as he added, “In terms of age.”

She was originally an adult, but a shut-in and useless person. She was used as an experiment by her younger sister, which is why she was turned into a little girl. It can be considered a way of making use of waste.

“Meipoli will have to agree, right?” Tsukikawa Shuu said with a smile.

“Mipoli.” Oyama Shinjiro thought for a moment, then nodded. “Alright, let’s go find her!”

“Let’s go.” Tsukikawa Shu smiled, and then took Oyama Mahiro’s hand.

……

Minami Oyama had just finished cooking.

"Ah, Tsukikawa-kun, would you like to have dinner together tonight? I made some for you too." Minori Oyama was still wearing an apron and holding a spatula in her hand.

Then, she turned around and froze instantly.

Tsukikawa Shuu and Oyama Mahiro are holding hands!

What... what on earth is going on? Minori Oyama was utterly astonished.

"Mepoli".

Oyama Mahiro took a breath, then hesitated for a moment, looked at his petite body, and added, "Mihara-neechan."

"I've decided to be with Tsukikawa-kun!"

"Eh?"

Minori Oyama was stunned. Then, she finally understood the meaning of those words, and her expression changed instantly.

"Hey hey!!!"

The kitchen echoed with a sound of utter astonishment from Minami Oyama.

At dinner time, the three of them sat down.

While talking, she gradually sorted out the situation and told it to Minami Oyama.

Of course, the part about the underworld is not fully explained, and we still need to take into account people's values ​​today.

"So, you two like each other, right?" Minori Oyama asked again to confirm.

"Hmm." Mahiro Oyama nodded, but his little feet under the table kept dangling restlessly.

Minori Oyama held her forehead.

“I don’t object to the two of you,” she said. “However, Tsukikawa-kun, do you know Mahiro’s current situation? Although she is an adult in age, her body is still at the level of a middle school student.”

“I know that.” Tsukikawa Shuu nodded, holding Oyama Mahiro’s small hand in hers, and smiled. “So I will wait for her.”

Minori Oyama looked at Hiiragi Tsukikawa, then at Mahiro Oyama, and finally sighed.

“Anyway, Shinji is old enough to make his own decisions now, so I won’t interfere,” Minori Oyama said.

"Really?!" Mahiro Oyama asked excitedly.

"Hmm, whatever you want." Minori Oyama said somewhat dejectedly, resting her cheek on her hand.

"Yay!" Mahiro Oyama exclaimed excitedly.

After dealing with Minori Oyama, night gradually deepened.

Mahiro Oyama escorted Hiiragi Tsukikawa to her doorstep.

"Bye-bye." Mahiro Oyama smiled and waved to Hiiragi Tsukikawa.

"Okay, bye-bye." Tsukikawa Shuuya turned around and smiled.

"Come again tomorrow," Masato Oyama said with a smile.

"Tomorrow," Tsukikawa Shuu laughed, "you can't play at home tomorrow, okay?"

"Huh? What should I do then?" Mahiro Oyama was completely bewildered.

"A date," Tsukikawa Shuu said with a smile.

"A date?!" Mahiro Oyama panicked a little.

She never liked going out, had never been in a relationship, and had no idea what dating was like.

The only experience I gained was from all that butter.

"With me here, you can leave it to me." Tsukikawa Shu smiled, took a few steps back, returned to Oyama Mahiro, and gently pulled her into his arms.
