As time goes by, facing the approaching "final exams", the girls become more and more nervous. They either lock themselves in the room to review, or find a place for special training.

But for Altina, these are all unimportant things.

After all, she had been to other worlds with Fang Zheng several times. As for the other world where Ciri was, she was not as interested as others, so she did not have a special desire to compete. Therefore, while others were working hard to review and train, Altina finished her homework step by step and then went out for a walk.

However, when Altina walked into the hall, she saw Claire frowning in front of the coffee table next to the hall, with a look of distress on her face.

"Claire, what's wrong?"

Seeing Claire's expression that looked like she was ready to go through fire and water, Altina walked up to her and asked. Claire was startled when she heard Altina's question and quickly raised her head to look at Altina.

"Ah, it's Altina. You really scared me... Aren't you going to review?"

"I'm not interested in that."

Altina shook her head silently.

"It's you, what happened?"

“Woo…”

Hearing Altina's question, Claire hesitated for a moment, but considering that Altina was a member of the Imperial Military Intelligence Bureau like herself, she still gave an answer.

"Actually... I'm thinking about how to... deepen my relationship with Mr. Fang Zheng."

"To deepen the relationship?"

"Yes……"

As she spoke, a blush appeared on Claire's fair cheeks.

"This is the order from the Prime Minister, but I don't know how to do it..."

“…”

Hearing Claire's answer, Altina tilted her head in confusion.

"Mr. Fang Zheng is a very easy-going person."

"Eh? That's not what I meant. Of course I know he's easy to get along with, but that's not what I meant."

Claire became more and more flustered, and then she stood up.

"I'm sorry, but this isn't a question I should be asking you. I still have work to do, so I'll be leaving now. Bye!"

After saying this, Claire turned around and left in a hurry, while Altina stared at Claire's back and tilted her head slightly. She didn't understand why Claire was so nervous. In Altina's opinion, Fang Zheng was not as difficult to approach as Prime Minister Osborne, and unlike those high-ranking figures she had met, Fang Zheng didn't seem to have any airs on weekdays.

Therefore, in Altina's opinion, if Claire just wanted to deepen her relationship with Fang Zheng, she could just invite him to have tea and chat together. Why did she have to worry about such things?

"Um?"

At this moment, Altina discovered a few magazines stuck in the gap between the sofas. They looked like they were hastily stuffed there by Claire. Altina reached out, picked up the magazines, and began to flip through them.

The sure-fire way to capture a man... Make him fall in love with you... Ninety-nine romantic nights...

Looking at the title in the magazine, Artina also showed an expression of understanding.

I see. This is what Miss Claire meant by deepening the relationship.

But why would the Prime Minister give this task to her when she is clearly here?

Thinking of this, Altina lowered her head, looked at her body curves, and made a comparing gesture.

“…”

Is this the reason? The Prime Minister judged that I don't have the charm of a woman, so he asked Miss Claire to come and deepen her relationship with Mr. Fang Zheng?

I feel very unhappy...

Altina frowned, feeling suddenly annoyed for some reason.

At this moment, footsteps were heard from not far away. Looking at the magazines in her hands, Altina hesitated. It was too late to put them back. Although this kind of book was not very clear, it was not something students should read. So she hurriedly took the magazines and secretly hid in the corner of the lounge. Then, Altina saw two petite figures, one black and one white, walking towards her.

I remember that it should be... Illya and Xiao Hei.

Looking at the two girls, Altina thought carefully. She didn't interact with these two people very much. Perhaps it should be said that the students in the academy rarely interacted with these two girls. Although she didn't know their true identities, from the intelligence she had collected before, they had a very close connection with Fang Zheng, and these two girls had amazing super strength.

Among the battles that have been recorded, Illya faced the "Sword Emperor", the executor of the association, and completely defeated him. And the girl named Xiao Hei was even more amazing. In the defense of Liberl Royal City, she fought one against three and defeated all three high-ranking members of the association, including the Saint of Steel. According to their self-introductions, these two people seemed not to be human, but some kind of heroic spirits... But there is no record of this.

The students at Semuria Academy didn't spend much time with the two girls. The two girls would often go out to explore and travel, and the only ones who interacted with them more often were Ling, Tio and a few other kids of similar age.

Although strictly speaking, Altina is not much different from them - at least on the surface.

“Aa ...

Xiao Hei fell headfirst onto the sofa, rolled over comfortably, and looked at Illya.

"I'm telling you, it's about time you let go a little."

"What are you talking about?"

Illya sat on the sofa next to him, staring at Xiao Hei with dissatisfaction.

"That's it, big brother. Don't you find it boring to always take half each? Why don't we do it together? It will be easier to deepen our relationship this way."

"You, what nonsense are you talking about! How can you say such things in public?"

Hearing what Xiao Hei said, Illya's little face suddenly turned red. She looked around uneasily, then looked away.

"I don't want to. You don't have to worry about what happens between me and my master!"

"Tsk, tsk, tsk, it turns out that experience makes a difference."

Looking at the angry Illya, Xiao Hei chuckled.

"I quite miss the impotent and furious you of the past."

"Ugh...that time...that is long gone!"

"That's why I said it, Illya."

As he spoke, Xiao Hei reached out and hugged Illya.

"We are sisters, so we should deepen our relationship. You have read the teaching materials I gave you before. If there are three of us, we can do more things. Don't you want to try it?"

“Uh… this…”

Faced with Xiao Hei's words, Illya also became hesitant, but after thinking for a moment, she shook her head vigorously.

"No, no, I don't want to be with you, Xiao Hei. You will definitely make fun of me!"

"Really? How come you are already an adult, but you are still so cautious and afraid of everything?"

Hearing this, Xiao Hei also showed a dissatisfied expression.

"You just think you're shy, don't you think I'm not?"

"I don't know what's going on with you. After all, Xiao Hei, you've always been like that..."

"snort."

Hearing what Illya said, Xiao Hei snorted, then let go of Illya and stood up.

"Forget it, just go on like this. Don't forget that there are many girls around big brother. Someone like you who has no interest in romance will soon get bored. I was so kind to give you some teaching materials that can help you and big brother improve your relationship, but you are so disrespectful!"

"You, you are angry..."

Seeing that Xiao Hei seemed really angry, Illya also became anxious and panicked.

"I, I don't mean that. I just feel embarrassed... No, I'm shy. Anyway, I'm not mentally prepared yet!"

"If you keep dragging your feet like this, by the time you're ready, I'm afraid your big brother won't know how many children he has, although the possibility is not high now."

Having said that, Xiao Hei sighed, patted Illya on the shoulder, and chuckled.

"Anyway, I've prepared the things for you. Remember, they're in the cleaning room on the right side of the bathroom on the second floor."

"Really? Why did you put it in a place like that? What if someone saw it?"

"This is convenient for you to use. Sister Eriri's skills are really getting better and better. To be honest, I can't help myself when I see you. If you can't help yourself, it will be easier to solve it over there, right?"

As he spoke, Xiao Hei turned around and left with a smile.

"Hello, wait a minute... Really!!"

Seeing Xiao Hei leaving, Illya wanted to shout loudly, but before she could finish her words, Xiao Hei disappeared in a flash. Illya looked at the key in her hand and hesitated for a moment.

"Oh... Let's wait a while before going... I don't think anything good will come of it..."

After saying this, Illya also left the lounge and took the elevator downstairs.

Until this time, Altina, who had been hiding nearby, quietly came out.

Although she didn't understand most of what the two said, there was one thing that Altina understood, that is, Xiao Hei seemed to have given Illya a textbook to improve the relationship between her and Fang Zheng. Although she didn't know what the textbook was, considering that both Xiao Hei and Illya were very close to Fang Zheng on weekdays, it can be seen that the textbook should be of great reference value.

I remember Xiao Hei said it was in the cleaning room of the bathroom on the right side of the second floor.

Originally, Altina didn't intend to meddle in other people's business, but when she thought of Claire's distressed expression just now, she suddenly changed her mind.

Maybe... you can look it up for reference?

Because it was the sprint period for the final exams, there were almost no people in the corridor. Artina followed Xiao Hei's instructions and quickly came to the cleaning room located in the bathroom on the second floor. Sure enough, next to the cleaning tools, there was a thin book with two girls drawn on it.

“Is that… this?”

Altina reached out, took the book from the shelf, and glanced at the cover.

"……?"

This seemed to be different from the magazine that Claire had referenced.

With doubt in her heart, Altina opened the small book in front of her.

To Altina's surprise, this book did not teach any knowledge like a magazine, but instead, it just told a story. It was about a pair of sisters who fell in love with a man at the same time. Both of them liked him, but neither of them wanted to give up, so they decided to conquer this man together. What followed was the romantic memories they had with this man in various places, including swimming pools, locker rooms, flower fields, night markets, groves... In the end, the two girls chose to join forces to fight against the big devil.

However, under the manipulation of the Big Devil, the touching sisterhood soon succumbed to violence and desire... and became the Big Devil's loyal slaves.

“…Ugh…”

Before she knew it, Altina's face had turned red, and she could even feel her heart beating very fast. Everything described in this book was completely beyond Altina's imagination.

But...is this the key to deepening my relationship with Mr. Founder?

Trying to suppress the intense beating of her heart, Altina turned to the end again and stared at the unfamiliar word.

"...Sisters' Donburi?"
