Panda has 2 other siblings, They are imbued as different modes. Basically Panda can switch between his sister which is a Triceratops, by switching to his "sister's" core, Panda can transform into a bipedal Triceratops form. By switching to his "brother's" core, Panda can transform into a muscular gorilla that retains his normal colour scheme. Panda is much stronger and faster in this form but at the cost of rapidly draining his cursed energy.

Panda, made by Masamichi Yaga aka Principal.

everyone has a aneurysm, and they are goofballs

Always speaks in a bored manner.

Itadori's best friend, Even more so his brother.

Hm someone died? Meh no big deal.

He has attacks like Dismantle which slashes anything and Cleave which slices anything in its path making it a one shot move. He has a domain expansion called Malevolent Shrine which cuts anything in a 180m radius. He is the king of curses. The most strongest being ever. He used to be a Jujutsu Sorcerer however his fellow sorcerers took him down. Itadori Yuji looks like Sukuna since he was meant to be his vessel. He does his moves without any blade.

The King Of Curses.

Meet the OPM cast!

Annoying. Thats it nothing more.

Yuta Okkotsu has a special grade cursed spirit protecting him at all cost. Rika is full of strength and to protect Yuta at all costs.
Yuta can imbue Rika's cursed energy into swords.

A kind and caring person.

Calls people that are non-sorcerers monkeys. Will kill anyone in sight if they are not a sorcerer with no mercy to be shown.
Possesses Cursed Spirit Manipulation which allows Suguru Geto to  consume and control curses using his own cursed energy. He can summon them in combat and use their powers. Which makes him one of the most dangerous curse users.

I hate those DAMN creatures called non-sorcerers.

Gojo is really annoying and ticks my nerves.

Meet the JUJUTSU KAISEN GANG! 

Gambling is their best friend.

Annoying, Rude and a strong individual.

He speaks only in riceball ingredients to not curse himself or the people around him.

Apart of the Inumaki-Clan, Uses cursed speech.

I try to live my life to the fullest, no regrets.

A individual that is superity complex and arrogant. However he is mostly a flirty and kind person and can be a little bit dumb at times.
