Going into the "invade Yggdrasil" arc, Kaito was almost like the one in charge. He was a capable leader and it was looking for quite a while like Kouta even might have ended up on his own, in a sort of "Kouta has the overwhelming power, but Kaito has the mind and resolve, the mental power, and the people around him" scenario. Now that Kouta's got his resolve, however, everyone is inexplicably flocking to him and, with the exception of Minato, it's like everyone and everything involving Kaito from the past 10+ episodes just got reset or rewritten for the convenience of the plot. A stark contrast to the guy who admitted his own tactlessness then proceeded to punch Ryouma for being even more tactless a while back.
