Horrified by what he's done, Kai challenges Aichi and reveals that what he's done hasn't caused anyone any happiness, and attempts to go into self-exile to amend for his crimes. In Episode 162, however, Kai shows a different side to him. Also, he appears to talk more towards Miwa. He seems more friendly and supportive towards Aichi. Although he retains his seriousness, he actually enjoys going to Card Capital and smiles quite often. He still is very much a serious person and is quite confident of him winning cardfight battles. His manga counterpart personality differs from his anime counterpart. When facing such a fighter, for example Kenji, Kai will remark on that strength, saying that it is what he has been looking for.
