Haruto attended to the opening of the Duel Team Carnival along with Orbital 7 to watch KaitoDuel and cheer him on. Kaito was against Haruto being there at first, and yelled at Orbital, but Yuma convinced Kaito it was okay. Haruto then timidly introduces himself to the other members of Team ZEXAL.
When the Litterbots go crazy, Haruto Dueled against one of them, but was about to lose. At that time, Kaito took his place and continued the Duel for him, defeating the litterbot.
