Chen Yu, he has many identities.

He is a gamer and a student at Hogwarts.

He is Tony Stark's savior and is also respected as the Second Supreme by the wizards of Kamar-Taj.

He was the victor of the Fourth Holy Grail War and El-Melloi II's student and greatest patron.

He was given the three Unforgivable Curses at the beginning and almost entered Slytherin.

His biggest dream is to explore the magical mysteries of different worlds.

What I want to do most is to fire an Avada Kedavra light cannon at the enemy.

"Attention, attention! Everyone, look over here, follow my lead. I have an announcement to make!"

"I, Chen Yu, the Sword Master of Avada, come and fight me if you don't agree!"
