She is a short and petite Merino sheep, with a thick, white coat of wool, and large eyes. She is an employee for a sportswear company and lives in the Hidden Condo with Legoshi as a neighbor. On the outside, Seven is polite and avoids conflict, even when her carnivore co-workers would belittle her by calling her "Lamb-chan". However, on the inside, she was frustrated and heartbroken over the way she was treated. When someone shows they respect her, she feels comfortable around them and acts friendly towards them.
