A typical Honkai Impact Reaction Story, nothing wrong here perfectly normal.

Reena Anemoi accidentally made a blunder during one of her experiments. Accidentally summoning vision holders from a world where her 'father's' gnosis was from. She was forced to host them, sadly, the former Geo Archon version of her father. Now, she has to find a way to safely get them back... "Dad! Stop trying to get laid!" Reena shouted in her mind as she watched Cerberus actively flirt with a girl and with some degree of success.
