[Kamen Rider] Brothers Getting Along in Kiva

Matsuno Seiya was a child his father didn't know about and no one had wished for. Then one day, a young man suddenly appeared and took him away. The man told him he was his big brother and took him to live in the biggest house and eat the most luxurious meals.

But his big brother wasn't home very often, and told him to wear this stone necklace whenever he went out, and to keep the little bat hidden away. Seiya didn't understand, but he obeyed.

Then one day, on a whim, he went outside and ran into a monster. Just as he pulled out his belt, he saw a young man across from him expertly holding the exact same little bat.

"Who are you?" / "Who are you?"

"Big Brother!" / "Little Brother!"

The two of them, one golden and one white, hugged their little bats together and shed tears of joy. Seiya and Beni Wataru tilted their heads in confusion in unison.

Taiga, arriving late, was stunned and stepped back. Two... two little brothers?

...Wait, doesn't that mean twice the fun!?
