Multiverse: SSS-Rank Treasure Chest at the Beginning

Chapter 290 290: Math Session

"Onee-san, I was just explaining a math problem to Tenya-kun, he's studying quite diligently."

Miharu quickly introduced, her face full of pride, as if she were showing off a precious treasure.

"Just studying?"

Mafuyu gently stroked her sister's head, then looked at Tenya, a subtle expression in her eyes.

"Thank you, Mafuyu, Miharu really helped me a lot." Tenya responded politely, a shy smile on his face.

"Miharu, you continue tutoring. I'll go prepare some fruit."

Seeing this, Mafuyu didn't say much more and walked to the kitchen, her steps light.

"Okay." Miharu returned to her seat and resumed tutoring Tenya.

(T/N: You guys know what tutoring means, right?)

In the warm atmosphere, the study progressed steadily. Under Miharu's patient guidance, Tenya conquered one difficult problem after another, and a harmonious smile occasionally appeared on his face. And Miharu, watching her junior's progress, was also filled with a sense of accomplishment.

In the room, only the rustling sound of pen tips on paper and Miharu's gentle explanations could be heard, intertwining into a beautiful learning symphony.

Tenya was enjoying Miharu's tutoring at the Touno family home, but he couldn't help but feel regret.

Originally, he had planned to experience a joint tutoring session with the sisters that evening, but he was targeted by the will of the great universe and couldn't carry it out. He could only find another way.

"This is troublesome now."

Mafuyu was busy in the kitchen, slicing fruit while recalling the reason for her sister's sudden visit.

In the past, her sister wouldn't visit so suddenly. Could it be true, as she said, that she just came to play with her?

Connecting this to her relationship with Tenya, Mafuyu couldn't help but feel a hint of worry. She was concerned that her sister might discover something, and even more afraid that her sister would be hurt. After all, Tenya's romantic life was too complicated, and she wasn't sure if her sister could accept such a person.

"Miharu, have some fruit before you study."

Mafuyu walked into the room with a fruit plate, saying softly. She placed the fruit on the table, her gaze inadvertently sweeping over Tenya, with a hint of scrutiny in her eyes.

"Thank you."

Miharu happily picked up a piece of fruit and handed it to Tenya. "Tenya-kun, you eat too."

"Thank you, Miharu, and thank you, Mafuyu." Tenya took the fruit and said politely.

He could feel Mafuyu's gaze but deliberately pretended not to notice, focusing on eating the fruit.

"Tenya-kun, are you very familiar with my sister?" Mafuyu asked seemingly casually, her eyes fixed on Tenya.

"Ah, yes, it's like this. We had some academic exchanges at school before. Miharu is very enthusiastic and helped me a lot." Tenya answered in a standard manner, trying to make his tone sound natural.

Miharu, listening from the side, nodded quickly. "Yes, onee-san, Tenya-kun studies very hard, it's just that some knowledge points are a bit difficult to understand, so I thought I'd help him."

Mafuyu nodded slightly, not saying anything more, but she was calculating in her mind. She knew Tenya's abilities, and in her opinion, it was unlikely that he would have many academic problems requiring her sister's tutoring. There must be another reason for this.

"Miharu, take a break first. I'll talk to Tenya-kun about some school matters." Mafuyu said with a serious expression.

"Okay, onee-san." Miharu obediently responded, then walked to the side and picked up her phone.

Mafuyu looked at Tenya, her expression becoming serious. "Tenya-kun, you should know what I mean. I hope you don't hurt Miharu, she's still very innocent."

"Mafuyu, please rest assured, I have no other intentions. I really just came to study." Tenya quickly explained.

"I hope so."

Mafuyu's tone carried a hint of warning, "I've heard about your affairs at school. Your romantic life is very complicated, and I don't want Miharu to get involved."

Tenya chuckled awkwardly. "Sensei, those are all misunderstandings; I'll handle them properly."

At this moment, Miharu suddenly interjected, "Onee-san, what are you two talking about? I don't understand."

"Nothing, Miharu, don't ask too many questions." Mafuyu said, her tone carrying an unquestionable meaning.

Although Miharu was a bit confused, she didn't press further. She felt that there seemed to be some secret between her sister and Tenya, but she couldn't figure it out.

Seeing this, Tenya quickly changed the subject, "Mafuyu, Miharu, I've met some interesting people at school recently. Shall I tell you about them?"

Miharu's eyes lit up. "Yes, Tenya-kun, tell us quickly."

Tenya began to recount his encounters with various girls at school, skillfully omitting overly ambiguous details and only describing some interesting daily interactions.

Miharu listened with great interest, occasionally letting out cheerful laughter, while Mafuyu listened quietly from the side, a hint of suspicion occasionally flashing in her eyes.

She couldn't believe that Tenya's interactions with those girls were so simple.

As Tenya spoke, the topic unconsciously shifted to some mysterious rumors at schoo, "You know what, there's always been a legend circulating at school about a bunny girl in the library."

Miharu's eyes widened. "A wild bunny girl appearing in the library? This can't be possible, right?"

Mafuyu , however, frowned. She had also heard a little about the strange bunny girl incident, the source of which was a third-year high school girl, Mai.

Tenya smiled. "I was just saying."

Miharu pouted, "Onee-san, I love listening to urban legend stories."

Mafuyu shook her head helplessly. "Alright, just make sure you don't get too carried away."

Tenya continued to talk nonsense with a straight face, inadvertently bringing him closer to Miharu.

Just as Tenya was speaking enthusiastically, his phone suddenly rang. Looking at the caller ID, it was Miko.

Tenya's heart stirred. Miko calling at this time, could something have happened to the Yotsuya family?

"Excuse me, Mafuyu, Miharu, I need to take a call." Tenya said, getting up and walking out of the room onto the balcony.

"Hello, Miko, what's wrong?" Tenya answered the phone, asking softly.

"Tenya-kun…"

On the other end of the phone, Miko's voice had a hint of a sob. "Mom suddenly got sick. Can you come over?"

Tenya's heart tightened upon hearing this. "Don't panic, Miko, I'll be right there. You take care of auntie first, I'll arrive very soon."

After hanging up the phone, Tenya returned to the room, looking apologetically at the Kirisu sisters.

"I'm really sorry, but there's an urgent family matter, and I have to leave immediately."

Seeing Tenya's anxious expression, Mafuyu didn't press further. "Go quickly. I hope it's nothing serious."

Miharu also said, "Tenya-kun, go quickly and come back quickly. I still want to hear your stories."

"Okay, thank you both. I'll come back to you after I've dealt with things." Tenya said, then hurried out of the home.

Tenya used Kamui and instantly arrived at the Yotsuya family home. As soon as he entered, he saw Miko with tear-streaked cheeks, while Touko lied on the bed, her face pale and her brows tightly furrowed.

"Tenya-kun, you're finally here." Miko, seeing Tenya, seemed to have found a savior and immediately threw herself into his arms.

"Miko, don't worry, let me check on auntie." Tenya comforted Miko, then walked to Touko's side.

He carefully examined Touko's condition and found that she seemed to have a severe flu. However, this was nothing to Tenya. He concentrated his energy and activated the Soul Apportion skill. His palm glowed with a soft light, and mysterious runes flickered within the light.

He gently placed his palm on Touko's forehead, and a fragment of soul slowly infused into her body. As the soul fragment entered, Touko's body trembled slightly, and her tightly furrowed brows gradually relaxed.
