Cocoa's older brothers that were briefly mentioned and appeared in a few flashbacks. Very little is known about them.
The brothers appear to be the same age, and may be twins. They both have pale brown hair, with one appearing messier than the other. One wore a dark blue sailor top with matching shorts, while the other wore a white shirt with dark green shorts. They appear a few inches taller than Cocoa; most likely being a year or two older than her.
Nothing about the brothers is known, except that they some times hung out with Cocoa and possibly respected Mocha. One brother is interested in becoming a lawyer while the other is pursuing a science-related career.
- They are the only known brothers in the series, along with Maya's older brother.
- One of them was voiced by Kaoru Harada in an episode of Season Two.
