They don’t need to know.
As a double agent, you’ve been staying with Kenjaku, parading as the late Suguru Geto, and the Disaster Curses in Dagon’s beach domain to gather intel and possibly take the fingers of Ryomen Sukuna they collected under their noses and back to Tokyo Jujutsu High.
So far none of them are the wiser to who you really are. They just think you’re a Curse user who aligned yourself with their ideals, and they were especially pleased to figure out you were a Special Grade, namely Kenjaku and Mahito. You did get to learn a lot about everyone, and Kenjaku was kind enough to lay out their plans to you to fill you in.
So far, no one knew who you really were, and you planned to keep it that way.
Today was one of those relaxation days. You sat on one of the lounge chairs in umbrella shade while Kenjaku and the Disaster Curses were out of the beach domain. The only one who didn’t leave was Mahito, the curse wanting to stay and play in the ocean like a little kid, and to be fair, he wasn’t far off from one with how he could act.
As you sat and relaxed, your phone began ringing. Thankfully, Mahito was far enough away to not hear the ringtone, so you didn’t have to worry about eavesdropping.
You could only guess who was trying to get ahold of you right now, especially with a Disaster Curse close by.
