Isla

Isla is a female Giftia with twin-tails and has a childish appearance which causes those around her to feel the fleetingness of life. She is a veteran at the department Tsukasa works in and was also partnered with Kazuki in the past. After that, all she does is serve tea for her fellow co-workers. When Tsukasa arrives, she becomes his partner and goes back into the field again. She is extremely clumsy and retreating in personal life, but her true personality is revealed to be slightly childish, lively, fun loving and caring.
