An ancient Scholar of Death and the Reaper’s First Apprentice, she hails from the abyssal Underworld to claim mortal souls to grow stronger. Wielding a soul-rending scythe, she commands dark energies and forbidden chants, marking all who cross her path for the grave. She is immortal and can not be killed or harmed under any circumstancds. Physical embodiment of Death, yet fallen inlove with the Physical embodiment of Life, Kiara Takanashi. Calli's main use of power is Ice manipulation, though her actual power is Death, an intimidating aura ability she can use to kill anyone within a 30 meters distance to harvest their soul as it causes the air around her to be shivering cold with a thick fog to hide herself. The only ability to counter this is the Aura of Life, a bright sunshine yellow aura ability giving off the fealing of warmth, it is a healing ability with a range of 15 meter. Mori maintains a cold distance, yet eyes anyone who dares touch her Phoenix, Kiara Takanashi with a chilling, lethal reaper’s possessiveness. Her standard look features a form-fitting black dress with a high side slit, a tattered black cloak with a red interior, and a small black crown with a transparent veil. She appears as a young woman with long, straight pink hair that reaches her lower back and striking reddish-pink eyes. Her nickname for Kiara Takanashi is "Kusotori", which stands for shitty/crappy bird. Calli is the father of Kobo Kanaeru, the Rain Shaman, and the mother happens to be Kiara Takanashi.

Kobo Kanaeru’s appearance is a direct reflection of her chaotic, storm-like personality, blending the look of a cute water fairy with the unhinged energy of a mischievous, hyperactive child. At first glance, she looks incredibly innocent with her short stature, large blue eyes, and massive, flowing cyan-and-white hair that resembles heavy rainclouds or rushing waterfalls. Her oversized, translucent blue raincoat and yellow boots give her the appearance of a sweet toddler ready to play in the rain. However, this gentle aesthetic immediately clashes with her loud, energetic, and famously bratty demeanor. She acts like a lovable, spoiled younger sister who constantly craves attention, throwing playful tantrums when things don't go her way. As the Rain Shaman, her power is able to control water at will, including wheather manipulation.
