A week has passed since Armored Rider Gaim debuted in the Inves Game and Team Gaim's popularity has since risen along with its ranks. Meeting up with Mitsuzane Kureshima as he got out of Tenju Private High School, Kouta reveals he found his Team Gaim jacket with the intent to rejoin the group. Meeting up with rest of Team Gaim, Kouta reveals to Mai that he quit his jobs to help in Yuya's place. After assuring Mai that it will all work out, Team Gaim begins their performance before Kouta wins an Inves challenge by Team Raid Wild. This turn of events, with Team Gaim now in third place, rattles Kaito before he is contacted by Sid who offers him a means to make thing more interesting in the Inves Game. Elsewhere, though he making money in the Inves Games, Kouta finds Akira disappointed with him as she could not accept money he earned from doing something that benefits him instead of the betterment of others. The next day, Kouta continues to ponder his thoughts on his sister's words before he is finds himself being criticized by Kaito over his inability to properly use his power. This results in challenge, with Kaito revealing he obtained his own Sengoku Driver and becomes the knight-like Armored Rider Baron. Intent to show what true power is all about, Baron is about attack when Sid steps in and deems a change of rules is needed while giving the Armored Riders Lock Vehicles so they can settle it in a race. However, the two end up in Helheim Forest with Baron taking out an Inves and marvels at his new power.
