One of IRyS's mascots and the counterpart to Gloom. A white cat with a triangle mouth and a single purple eye mirroring its owner’s heterochromia. Its fur is patterned like a tuxedo with accompanying bowtie. Has a single detached wing on its left side.
Bloom was designed by Hololive English vtuber Tsukumo Sana with input from IRyS and her chat.
