[The CP is Professor Snape. He might come through from Snape's world later. Our baby Salin belongs to Slytherin.]
Good news: he transmigrated and didn't die.
Bad news: he transmigrated into Jujutsu Kaisen.
As a seasoned otaku, Salin knew how dangerous the Jujutsu Kaisen world was, so he hadn't planned on getting involved in the main story. But can someone explain why he transmigrated straight into the scene where Itadori swallowed the finger?
And another thing! Why did he wipe out that cursed spirit with a single Avada Kedavra?
Salin: Hold on! This can't be right! Isn't this Jujutsu Kaisen? Why is Harry Potter crashing the party?
Also, why is he covered in blood and wearing a tattered Slytherin uniform?
This is a disgrace to his image!
If he's already transmigrated and has magic, wouldn't the Harry Potter world make more sense?
Salin is shocked. Salin is confused. Salin wants to snuggle up with Professor Snape. QAQ
As the saying goes, when in Rome, do as the Romans do. As a Slytherin, it's only natural for him to know some Dark Magic, right?
Heh heh, sharpening his blade for the higher-ups.
