I think what they were wanting to go for is that Coco's mobility is severely decreased while her weapon is in gun mode, which is why she had Yatsuhashi just standing there next to her in the tournament. His job was to guard her while she tried to mow down Mercury and Emerald with her gun. He did manage to block Mercury's drop attack, at least.

Yatsu pushed Coco out of the way of Merc's attack and then blocked Merc with his sword.
