Kami-sama

As the supreme deity overseeing the divine realm, he accidentally struck the protagonist Mochizuki Touya with lightning, ending his life. Overcome with remorse, he chose to reincarnate Touya in another world, granting him a reinforced physical body and a smartphone as compensation. From that point on, he frequently contacts Touya by phone to offer guidance and advice, and occasionally descends to the mortal world disguised as an elderly human man to meet him in person. He is a remarkably warm and caring god who looks after those in his charge.
