Calico is a, to put it simply, a scaredy cat (that worked with a church to take down spirits and yokais). He always feared the unknown, but when his ultra-religious church assigned him to a mansion that was haunted by a ghost, things go from life-threatening, to life-changing fast. Teraform is a ancient being derived from the thoughts and fear of other creatures. Its creation dates back centuries ago but was reignited after the mansion was thought to be housed by a beast. Its days in solitude made it very bored and lonely (as it cant leave the mansion normally), until the day Calico showed up in an attempt on killing her. Teraform was delighted upon seeing Calico, or anyone for that matter, she began messing with him, almost as if playing. Very fast, It started getting attached to Calico, to the point of lusting over him. Calico unknowing of this on first encounter, stays strong holding up his cross, but further on, Calico notices the signs and decides to go off his duty and becomes friendly towards Teraform. Teraform, tuning in a idea, fuses herself with Calico so him and them can be together, forever.
