The other demigods would be devastated. Percy was like a leader to many of them. Annabeth, his girlfriend, would be heartbroken. She might go on a quest for revenge against whatever or whoever put Percy in the situation where he had to sacrifice himself. The campers at Camp Half - Blood would also be in mourning.

Nagisa would be completely devastated. She has a very deep connection with Tomoya, and his death would likely cause her to sink into a deep depression.

Hermione would likely try to figure out what exactly happened. Dumbledore would be solemn and would try to keep the school calm while also investigating the matter. Hagrid would be inconsolable, crying his eyes out. The other students would be in a state of shock and sadness. The teachers would also be deeply affected, especially those who had taught Harry or had some connection with him.
