This coaching is not right.

"Hoshi no Miya, I've got it."

"I can use this forget-me-not as the core of my spiritual power."

Teacher Hoshinomiya was taken aback for a moment, then smiled approvingly. "That's a good idea, Chabashira. This flower is of great significance to us. Using it as the core will make your spiritual power more stable."

Teacher Chabashira nodded, closed her eyes, and began to try to condense her spiritual energy into a four-petaled forget-me-not, then surrounded the forget-me-not with her spiritual energy.

This time, her mental energy was no longer scattered as before, but slowly revolved around the forget-me-not, gradually forming a weak but stable core.

Teacher Chabashira's brows gradually relaxed, and a hint of surprise appeared on her face. "I did it!"

Ms. Hoshinomiya smiled and nodded. "See, you did it. This flower is a testament to our friendship."

Ms. Chabashira held the forget-me-not with a missing petal tightly, her eyes filled with gratitude. "Thank you, Hoshinomiya. I will cherish this friendship and this strength."

From then on, under the guidance of Hoshinomiya-sensei, Chabashira-sensei continued to practice and improve. Although her spiritual core was still based on that forget-me-not, Hoshinomiya-sensei could always recognize it at a glance.

Every time Hoshinomiya-sensei sees that four-petaled forget-me-not, she is reminded of the day they met, and that forget-me-not with a missing petal. That was the beginning of their friendship, and also the starting point of Chabashira-sensei's method of applying spiritual power.

As time went by, they went from students to teachers, but that friendship could never be the same again.

Looking at the forget-me-not in the core, which was missing two more petals, I was filled with emotion.

Their friendship was like a flower with a missing petal, forever leaving a regret.

......

Finally, Sakayanagi led the Class A members to stand in front of the central room.

Her brows furrowed slightly, a nameless unease lingering in her heart.

Her intuition told her that something was wrong, but she couldn't quite put her finger on it. This uncertainty made her decide to act cautiously.

"Katsura, you all go in first." Sakayanagi's voice was calm, but carried an undeniable command.

Yahiko and several other Katsuragi students were dissatisfied, believing that Sakayanagi was using them as cannon fodder.

Their voices were filled with complaints and resentment: "Why are we the ones who have to go? Why aren't you allowed to go?"

Katsuragi waved to stop their noise, his eyes revealing determination: "Alright, do as Sakayanagi says. Let's go inside first; it'll be safer that way."

Katsuragi knew that Sakayanagi's intuition was often very accurate. If she sensed something was amiss, they should not take any risks. His own ability, which granted immunity to most situations, was indeed the best option.

He took a deep breath, then carefully opened the door and stepped inside first.

The room was dim and quiet, with only a few rays of sunlight filtering through the window casting dappled shadows on the floor.

With his mental energy fully activated, Katsuragi vigilantly observed every corner of the room, searching for possible traps or hidden enemies.

The other students from Class A followed closely behind, spreading out and each taking charge of a direction to ensure that no threat was overlooked.

Although Yahiko was somewhat dissatisfied, he understood that Katsuragi's decision was for the benefit of the entire Class A, so he didn't say anything more.

Katsuragi and the others checked the room thoroughly, and after confirming there were no traps or hidden enemies, they came out one by one. Katsuragi believed the room was safe and decided to let more classmates go in to move the energy stones.

Sakayanagi frowned, still feeling somewhat uneasy, but seeing that Katsuragi and the other classmates hadn't noticed anything, she eventually agreed to the suggestion.

However, out of caution, she and several of the core members, including Hashimoto and Kito, chose to stay outside.

Ms. Chabashira observed all of this from the shadows. She noticed Sakayanagi's caution and couldn't help but admire him inwardly.

However, the students in Class B were already close to this area.

Teacher Chabashira decided not to show up, but to hide to the side and quietly wait for them to meet.

Led by Ito Sawa, the students of Class B quickly and quietly approached the top floor. Their mental focus was highly concentrated, ready to deal with any situation that might arise.

Ito Sawa led the way, his sharp eyes warily observing everything around him.

As Ito Sawa led the group past the spot where Chabashira-sensei was hiding, he glanced back in her direction one last time. Though he didn't speak, a knowing look flashed in his eyes.

Teacher Chaba quickly realized that he was the one who had investigated the entire scene.

Ito Sawa knew that Chabashira-sensei was there, but she did not make contact with Class B as he had just sensed.

It seems that Chabashira-sensei doesn't intend to remain neutral, but rather has his own plans.

It seems we have another bargaining chip to use against Class A.
