All the Contract Messengers Are Turning Evil [Jujutsu Kaisen]

[Irregular updates] Hello, I'm a magical girl whose magic stopped working because my crystal broke. Could I ask you to make a contract with me and help me find it? As a reward, I can give you magical-girl powers! Everything above is a lie. I'm actually a dark overlord, sealed on Earth by the magical girls' power of light. With no other choice, I have to seek out Earth's strongest champions. After a series of twists and turns, I successfully tricked Gojo, Geto, and the others into making contracts with me, and we set out to crack the mystery (crossed out) find the crystals. Along the way, we forged a deep friendship. To make them trust me more, I took on all sorts of roles, learning to spread love and justice like a magical girl, and talking with them about life and ideals The day we gathered all the crystals arrived. I was overjoyed. After insulting them with a string of remarks like "Men really are idiots," "You deserved to be used by me," "Did you really think I was a magical girl?" and "You're unbelievably stupid" I failed to use the crystals to leave, as I had planned. I saw my contracted champion, Gojo, holding a crystal. His usual flippant smile was gone, replaced by a familiar anger at being betrayed, though this time it was strangely calm. My other contracted champions were the same. The warm illusion from before had been shattered, and suddenly they were terrifying. "Want the crystals?" Key points: The heroine is not the true, good, and beautiful type. There will be various dark-turn storylines. Yuta and Rika are not a couple. Theme: Be an honest person.
