[Honkai Impact 3rd timeline: lighthearted, sunny, healing, mostly slice-of-life scenes]

A soul from another world brings a new variable to this established story, creating a new collision with the existing beings.

From the moment they arrived at their new house and started attending their new school, their fates, which should have been unrelated, became intertwined.

From the day we met, the Honkai was born.

A reclusive boy awakens a power—is that power a curse of destruction? Or a gift of fate? Or perhaps… something that was always meant for him?

He was simple, yet everything about him seemed shrouded in mystery. What kind of turmoil was hidden behind that mystery?

"If it is true that with great power comes great responsibility, then I am willing to shoulder this responsibility, to find the truth, to find... my true self!"

The past and the future intertwine, forging the hope of today. In those ordinary days, new bonds will connect us, giving us the courage to move forward.

"Don't be so surprised. I told you, I'm very strong. I'm not that easy to get into trouble with."

In the end, he may be battered and bruised, or he may return in triumph, but in any case, he will hear that familiar phrase:

Welcome home.

[Slightly hardcore] + [A huge number of self-created academies and students] + [With both angst and sweet moments] + [Daily life/battle]...

Thirty years ago, the Seventeenth Joint Campus was destroyed by an unknown force, turning the once prosperous academy into a desolate ruin. Our forefathers fought desperately during the catastrophe, sacrificing their lives to give their descendants a chance to survive. However, the survivors still wander among the ruins, lost, helpless, and uncertain of the future.

Just as despair was spreading, a firm voice rang out:

"Reconstruction, revival, revenge."

Guided by this brief yet powerful message, the students of Campus 17 wiped away their tears and rose again. They rebuilt their homes from the ruins, unearthing buried scientific discoveries from the depths of the rubble, etching the tragedy into their hearts and transforming past pain into motivation for progress. Beneath the wasteland lies not only a shattered civilization, but also revelations powerful enough to change the future.

Thirty years later, when a similar disaster struck another school known as "Children's Eden," the students of the Seventeenth Campus resolutely raised the blade of revenge. They were no longer helpless survivors, but fighters who had overcome the shadow of death. With thirty years of accumulated experience and the strength forged from the ruins, they would safeguard hope and reverse their fate.

"The past belongs to history, but we remember it."

"What is now ruins, we will rebuild."

"The future belongs to hope, and we create it."
