Teased for being a generic hero by the rest of the cast and often overlooked by the developers, Kai is a plain, jack of all trades character with a unique stat build. Kai has a single point boost to his attack stat and no other stat or passive related penalties, which is extremely significant, given that he is one of the only two characters on the roster to feature the advantage of an attack modifier without a penalty (the other being Ellie). Consequently, Kai is able to play both aggressively and passively, but the nature of his stats and hyper lean more toward aggression. With 5 health, Kai is able to survive most attacks dealt against him, especially when his health is near full, and his extra attack enables him to both deal with most panels with relative ease and deal decent damage to opponents. As a result of his neutral stats and nonspecific purpose, Kai also has the advantage of being able to use most cards, as he neither suffers much nor becomes extremely powerful from any particular card. He can, however, benefit greatly from battle cards such as and when pursuing and and when defending. Lastly, while not fully protected, Kai is mostly immune to which is another minor but positive trait the player can take advantage of.
While his stats are unique, Kai's main vulnerability stems from his lack of other modifiers. Although Kai does not feature any noteworthy exploitable weakness, the results the player will yield are completely random due to the lack of certainty provided by neutral stats. Kai's attack stat can carry him through his attack roll, but his lack of defensive modifiers enables the opponent to quickly chip away at his health if the player fails to either KO them quickly or defend well against their counterattack. Consequently, Kai can be defeated through constant combat as he only has neutral survivability without any protective cards. Likewise, Kai's neutral defense and evasion stats are not ideal when facing apanel or powerful attacks of 6-7, even with his decent HP. Owing to this fact, the player should generally try to avoid slowly progressing multiturn confrontations until they have battle cards in their hand to compensate for the shortcomings of his defensive stats.
Like most characters in the cast, Kai should generally aim for star norma, but he can play either side depending on the player's luck or the board. If the player is having a good run, +1 attack can go a long way, and Kai may eat up a lot of opponents and panels. Fortunately, Kai can hold his own on combat-based boards like Tomomo's Abyss and against bully characters thanks to his attack and HP. Like most neutral characters, however, it is generally best practice to play passively unless the opportunity presents itself, and the player should hold onto their hyper and combo it with another card for a power play later in the game. The player should mainly aim for panels but should take care to make sure they have cards in their hand for later, especially Kai's hyper.
