(SPOILER WARNING)

In a white vast expanse that seemingly never ends, there stood a golden being with the silhoutte of a- of a- Nani!?!?!?

A golden finger!!!

Yes it was a golden finger. Its body exuding an aura that of a benevolent god. Seemingly beconing the Narrator to come closer. And the Narrator did go closer to the Golden Finger

(POV Golden Finger)

Well hello valued reader, you seem to have come here by accident or seeking answers to your problems, well then you have come to the right place.

First

Save and Load - it allows him to Save the state of an Existence and Load it back

Save and Load cloning - dividing a part of an existence and loading the divided part allows it to become a full existence

Why do the clones have different personality you may ask.

- Well even if they were sharing memories, they still had different experiences, and those experiences dominate the shared memories, as if just looking at the show but experiencing it first hand. So yes.

Why does he fucking cut off his fingers

- well then you see, the finger could easily be bitten off like a carrot, also for convenience and training pain tolerance at the same time. And becaue I would be an important character in the story. Yes, me, the golden finger

Why does he laugh suddenly at the start and always do some dumb shit

- i could say its because of bad writing, but plot wise, lets say its because of his background, and dont worry at ch 5 his character got better

Zanpakuto - basically by integrating a part of his existence onto another existence, once he save and load it back it will now be part Braun. Also because its bullshit.

Well hello there, you may have come from Attack on Braun and saw BJ transform and youre like wtf?!?!?!?

Well then let me explain.

Existence Invasion - by inputting a part of his existence onto other creatures like a part of his body like finger or semen. He will be able to save and load the existence with a part of him. By the power treating them the same existence, the Braun part overrides the Original Existence and make it part Braun, allowing it to save and load and have access to the GC. And once they load the Memory save file of all Brauns, they are now officially part of the Braun Legion

You could send some question in the comment section and I will do my best to answer them
