Lan can't believe that his dad would give a SynchroChip to Chaud, but that's exactly what Dr. Hikari did. And even worse, he reveals that Chaud and ProtoMan had a stronger CrossFusion than Lan and MegaMan! Lan has to run off on an errand for Maylu, but it turns out that the errand was just a trick by Yai to get Lan, Maylu, Ms. Mari, and Rush into an elevator that turns into a robot and flies them to KingLand. The data from Ayano Tech's latest video-game has been stolen, and it's up to Lan and his friends to get it back!
