I'm so tired from all that training day after day. But I'm awake now that I've seen such power!Shin
Shin, like all creatures who had a strong faith in the gods, can see Amaterasu's red markings, however, he does not know that they are the markings of a god and instead thinks it to be a new style. He comes across as being quite lazy, always expressing his fatigue. Despite his laziness, he will leap into action with the other Canine Warriors when necessary.
After defeating Ninetails, Amaterasu can challenge the Canine Warriors, renamed Kusa 5, at the Gale Shrine for Stray Bead #35. Shin appears with Rei, Ko, Chi, and Tei, sharing the same attacks. When the battle starts, Amaterasu can immediately approach him and begins her assault with farming techniques. After the farming procedures are completed, Amaterasu has to focus on offense while simultaneously defending from the attacks of the other Canine Warriors. When Shin jumps into the air and perform a somersault before landing, his Faith Orb glowing, Amaterasu has to run to a certain distance, wait for Shin to lunge at her, and when he has covered half the distance between his original position and Amaterasu's, execute a Sub-Reflector Counterattack to gain a Demon Fang and defend from the attack. Other attacks of the Canine Warrior includes a series of multiple lunge and bites, a hole-digging attack, and a land mine attack. When sufficient damage is dealt, Shin will be stunned, a chance for Amaterasu to deal further damage.
