(Jujutsu Kaisen Crossover) How to Reject Love as the Clan Head

Tianmanwu Li got her hands on a pixel-style life-simulation game with a tacky name. She gave herself an incredibly awesome identity and appearance, then set off on her journey to dominate the world of jujutsu.

...Not! (Flips the table)

Today, she accidentally handled a file incorrectly and her reputation dropped. Tomorrow, she failed a mission and a trusted subordinate died. Every so often, NPCs hurl insults at her and discriminate against her for being a woman... She's sick of this life as a lowly underling.

So Tianmanwu Li stopped playing by the rules and decisively paid to change her fate.

The higher-ups who can't stand me? I'll secretly kill you tonight and dump your body in Tokyo Bay, teehee.

The elders who boss me around? I'll secretly kill you tonight and dump your body in Tokyo Bay, teehee.

You love running your mouths at me, don't you? I'll kill your whole family tonight, teehee.

Theme: I just want to quietly be the head of my family. You can all quietly be my tools.
