Kai (カイ Kai) is one of the four starting characters in 100% Orange Juice!, that the player can select when creating a new save file. He originates from and is the protagonist of 100% Orange Juice!.




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 the only character on the roster to feature the advantage of an attack modifier without a penalty. 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  Encounter 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  Accel Hyper and  Super All-Out Mode when pursuing and  Rbits and  Rainbow-Colored Circle when defending. Lastly, while not fully protected, Kai is mostly immune to  Reverse Attribute Field 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 a  Boss panel 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  Encounter 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  Bonus panels but should take care to make sure they have cards in their hand for later, especially Kai's hyper.

Protagonist's Privilege
Protagonist's Privilege.png
Effect Duration: 3 chapters
When you are allowed to attack first, the opposing unit cannot attack (once per combat).
Hyper Info
20 ★
"This is the privilege of the main character!" - Kai


Kai's Hyper is Protagonist's Privilege. When used, if the player attacks first in battle, the opposing unit will skip their attack roll. This effect lasts for 3 chapters.

If the player attacks first in a battle with multiple rounds of combat (due to effects such as Little War), the opponent will only skip the first round of combat.

If Protagonist's Privilege is used while it is already in effect, the effect itself will not stack, but the duration will be refreshed.


Protagonist's Privilege is an unusual Hyper in that it has no blatant damaging or protective effect on its own, relying solely on combat to activate it. While not particularly powerful on its own, the main advantage of Protagonist's Privilege is that it enables the player to take risks and remain safe while doing so, as long as they strike first. For example, the player will be able to enter a  Boss battle with 1 HP and leaving unharmed, as the boss will not get to attack. This method of shielding against the boss is a very common use for the Hyper and is advisable in multiple scenarios. Or in another situation, if the player is pursuing a low health opponent, they can keep attacking the opponent until they are KO'd without the chance of being KO'd themselves. To get the best results out of the Hyper, the player should generally activate later in the game to help them defeat the boss or weakened opponents, and then possibly pair it with a battle card. Using  Final Battle while the Hyper is active will let Kai get a free attack roll against a defending opponent before the combat phase acts as normal and  Accel Hyper can be used to strike the opponent hard. More specialized plays are possible as well, such as using  Dark Side of Business without the risk of retaliation damage after stealing the opponent's stars. Best of all, the player will have 3 chapters to deal as much damage as they can and catch up to far opponents if needed. Overall, the card gives the player a lot of choices, for what they want to accomplish with the card.

Despite its advantages, Protagonist's Privilege has its flaws. Firstly, the Hyper is not cheap at a cost of 20 stars, and using powerful combos to bring the card to the maximum potential will often cost the player around 50 stars. Thus, using  President's Privilege is beneficial in lowering the cost but will result in the player using their entire hand to make a combo, leaving them vulnerable if an opponent approaches, especially in the late game. Thus, it may be in the player's best interest to mainly use the card for the Boss. The second and most blatant issue with the card is that unlike other Hypers, it does not do anything, as in it does not deal damage or steal stars on its own. If the player wants to take advantage of the Hyper, they can only do so through the course of raw combat, not a "super card" that automatically does the heavy lifting for them. Lastly, the most obvious weakness is that Kai must attack first to get the benefit from the effect. As a result, the Hyper lacks usefulness when all opponents are behind Kai and leaves a massive window open for the opponents to assault the player even when the Hyper is active.


Playing As Kai
  • Similar to bully-type characters, Kai can benefit from cards that cause battles such as  Gentleman's Battle and cards that increase his ATK in battle like  Accel Hyper.
  • Cards that increase Kai's movement such as  Dash! and  Windy Enchantment can be helpful in catching weakened opponents.
Playing Against Kai
  • As Kai's only strength is his extra attack, cards that protect the user such as  Shield and  Shield Counter are effective against him.
  • Cards that cause Kai to lose cards such as  Gift Exchange and  Present Thief are helpful in making Kai lose his hyper, rendering him relatively average.

"This is the privilege of the main character!" ―Kai


In Co-op mode, Kai's REC stat is increased from 5 to 6, due to his base ATK of +1. Kai's passive does not change.

Kai's Hyper, Protagonist's Privilege, has a different effect in Co-op. When used, the player will always attack first in battle and the opposing unit will skip their attack roll. This effect lasts for 3 chapters. (In all other aspects, this Hyper functions similarly to its Normal mode counterpart.)

Bounty Hunt

Kai's passive and Hyper are unchanged in Bounty Hunt mode.

Kai's base stats give him 30 starting stars and a markup of +25% at shops.

Starting Cards

When the player begins a new game and selects their starting unit, they will receive 15 standard cards that can be used immediately to build a player deck. If the player selects Kai, the 15 cards listed below will be received.

In concurrence with Kai's stats, Kai's starting deck is relatively combat based, with it containing mostly stat adjustment cards to aid Kai and weaken his opponents.
