As a child in the Originia flashback, Crea has short, messy, dark brown hair. His eyes are wide and bright blue. He wears a white shirt with a black jacket sewn to his shoulders like a cape, and has yellow shorts. A white bandage covers his nose, the reason for it is unexplained.
When he initially gets his body back from Rchimedes in Volume 2, he has very messy and somewhat spiky black and white (questionably blue) hair. He was given the shorts and shirt from Alba's Maou outfit, so he wears a red shirt with a popped collar and green shorts.
In Volume 3, Crea retains the hair. He now wears a dusty beige shirt, black shorts, and has a black bag with an over-the-shoulder strap on his back.
Crea is very excited and bubbly, to say the least. He seems to be fascinated by most things, and willing to try anything new. Though he is generally very dense, he has moments of clarity and perception, like when he pointed out Alba's belts or judged Foyfoy's willpower to stop Lake. Like a child, he sees things differently than everyone else and will likely always speak his mind.
Crea is Ross's best friend. Ross seems willing to go to any length to make Crea happy, and seemed dedicated to their childhood dream of travelling the world together. Ross mentions that he's happy with a simple life with Crea at his side, but gets very prickly when Crea mentions that he feels the same. It's likely that Crea looks up to him as well, as he copies Ross's keigo to try and make a good first impression on Elf.
Crea probably looked up to Rchimedes as well and saw him as his family. He calls him 'Uncle' in the flashback scene. It's hard to say how Rchimedes felt about Crea, but in the end he still saw him as an object referring to Crea's existence more as a thing when he hijacked his body. Crea never really addresses how he feels about Rchimedes after the fact.
- His catchphrase is "Seriously?! That's amazing!!" and varying translations.
- His name is often translated as Claire.
