Tide and tiger

Aotsuki Ushio, a junior high school student, lives with his father who is the abbot of the temple. One day, he encountered something incredible in the basement of his warehouse. It was a big monster who was terrified by the people as a vicious monster and sealed by the "beast spear" for five hundred years! The tide that pulls out the spear is about to be eaten by the monster! But at the same time, due to the power of the "Beast Spear" that had awakened from his sleep, he instantly smashed the other monsters that had gathered monster energy. Stunned by the power of the spear, the big monster, who asked for cooperation without thinking, was given the name "Tora", and the two began to act together. In this way, the boy who became the inheritor of the "Beast Spear", the "Tide&Tiger" combination with the big monster was born. After that, they defeated the monsters that came one after another and were involved in the grand battle for the survival of the world.
