Before going to bed, he reads books about practical knowledge he's interested in, so he has a habit of falling asleep in the position he reads. Because of the environment he grew up in, he didn't have a chance to receive a formal education, but you can see many scenes where he shows a high level of intelligence. While he's only 15 years old, his knowledge in a particular field is at the same level as a specialist's.

At present he secretly enjoys observing the original machinery structure and systems inside of a Circus Ship. He also thinks of investigating the sheep sooner or later.
In Gareki's name, "Ga" means "flower" and "reki" means "gravel, small stones."
