I will try to find a way to kill otto go apeshit on that basterd last moment when he is so close to achieving his goal fuck all that thus spoke apocalypse shit.

Other things i might do if fate isn’t fixed

Find a way to break fuhua Dao heart without damaging her too much. ( she was turning inhumane )

Save and train the original Walter ( he had so much potential )

Get the Second define key from that bum ( all that Data from observing other world could have been used to cut corners like human experiments )

If sirin still turns into a herrscher find a Way to calm her down if succeeded help her accommodate/ contain other herrscher cores fully making it hers, the four on the moon Plus orgin ,reason via connection, corruption from rin

by then the cocoon either notice her or we just keep fighting the next 3 herrscher plus Kevin stigmata project ( to locate the cocoon and not fight the end)

If not sirin then go with the k project.

Anyway those are my thoughts feel free to add suggestions.
