Prinz

He displays and takes great care of gifts he receives.
Squidkid Jr. gifted him a pair of his shoes, but Prince hasn’t been wearing them.
Prince reached out to the son of his household's gardener, Laceless, and invited him to join their new team.
His name (in the English version) is German for Prince.
their parents, despite Emperor's being the crowd's favorite, obviously give equal love yo both of his children.

it is a theory that both Emperor and Prinz are cousins or at least related to Pearl Houzuki.

At first, Prince is reserved and quiet, watching his brother command him and his team. He showed reluctance but just followed orders as he was told to do. During the Square Cup Final against Blue Team, he observes their battling style and is inspired to have fun and try new tactics Unlike his older brother, Prince is more empathetic and friendly, but is shown to be just as determined and hardworking as his older brother is. despite that, people still choose Emperor more. which he, genuinely, dislikes.

As a typical Inkling, Prince has a round face, pointed ears, and sharp teeth. He has fair skin and shorts. His hairstyle is reminiscent of Emperor's, being shaved on one side and all six tentacles slicked back, except that the front tentacle covers his face slightly. His tentacles and eyes are sun yellow, but can change color at will. He wears the Eminence Cuff, Milky Eminence Jacket, and Milky Enperrials. he's... SLIGHTLY weaker, but it's only because his emotions get the best of him. he's legitimately paler than his brother and people often and genuinely think he's sick. he has a bit of freckles, barely noticeable.
