[Genshin Impact] Every Time I Reincarnate, I Get Another Big Brother

Collei, a trainee forest ranger, died during a patrol beneath a fireball from an Abyss Herald.

When she opened her eyes again, she discovered she had somehow gone back more than a decade and become Tighnari's master's younger sister?

But can someone tell her who the Greater Lord Rukkhadevata is?

At this point, so many things have yet to happen, and so many regrets can still be put right.

The Loom of Fate continues to turn...

At last, she returned to her original world, only to find that all her brothers remembered her now!!

Collei: (catlike screaming)

World One: Little Tighnari's sister, some things are too painful to forget

World Two: Xiao's sister, escape the Dream God and welcome a bright future

World Three: Scara's sister, Collei says she's wanted to beat up the Doctor for a long time

The remaining worlds are undecided

Collei is the darling and sole female lead. A no-couple story about saving everyone, and everyone is family!

Theme: Having suffered myself, I hope the world can be free of regrets.
