Once a normal human from Earth, Zeranno was reincarnated in another world in the form of an insignificant slime. Alone, he's not much of a threat, but with allies, he can be a powerful force to be reckoned with. His humanoid form is derived from Anna, a dragonewt girl who was on the verge of death. Since their first meeting, they've fused together, now sharing a single core. As a result, Zer has become a dragonic slime, fused forever with her. Being a unique instance of a sapient slime, Zer possesses many unique abilities. He's able to manipulate the consistency of his body fairly freely, letting him release elastically charged blows or change colors. He can also borrow the powers of individuals he's absorbed. His union with Anna has given him an affinity for the element of lightning, also granting him immunity to and control of electrical energy. As a reincarnated individual, he also possesses a special power in addition to that, in his case, a pocket dimension held within his core. In that dimension, he can mold space to his will, making him much like a god. Outside, however, his abilities remain limited to those granted by his species and friends he’s absorbed. Along with Ichigo, he helped found the Two Tales adventuring guild in Valassia. He now lives there with his allies, his pocket dimension serving as their headquarters.
