Tei (「悌狗」?; Teikō; dog of brotherhood/dog of respectfulness) is a member of the Canine Warriors, being the last of the five found in Kusa Village. He challenged Amaterasu to a fight to prove her right to bear the Canine Tracker she had, but after that he apologizes for his behavior to Princess Fuse when she appears.
Princess Fuse forbids me to join in fruitless battles, but I want you to prove your right to bear the Canine Tracker!Tei
Tei is a pink/magenta Tosa-Ken dog. He wears an orange bandana with the Orb of Brotherhood around his neck. He has a short muzzle and short drooping ears, with a lost right eye.
The first encounter with Tei is at Kusa Village, after finding the first four Canine Warriors and then going to ask Princess Fuse how many dogs have Amaterasu found. Tei will be waiting in front of the priestess' residence, waiting for Amaterasu, questioning her rights to bear the Canine tracker, eventually challenging her to a fight to judge her worth.
"'Tei' stands for 'brotherhood'.
Brotherly affection breeds understanding.
It allows us to be ourselves and accept our fate..."
Tei is not at all a difficult opponent. 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 attacking Tei while simultaneously defending from the Canine Warrior's offense. When Tei jumps into the air and perform a somersault before landing, his Brotherhood Orb glowing, Amaterasu has to run to a certain distance, wait for Tei 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. Another variation of this attack is a series of multiple lunge and bites. When sufficient damage is dealt, Tei will be stunned, a chance for Amaterasu to deal further damage.
