Mei (メイ Mei) is one of the playable characters in 100% Orange Juice!. She was added to the game in DLC 18Mei & Natsumi Character Pack.jpg alongside Natsumi.


  • Gain  Red & Blue when holding no cards at the end of turn.


An antagonistic and extremely competitive girl, Mei is always ready for a fight with whoever she deems as her nemesis, with the help of her penguins Red & Blue. Mei herself is a balanced character with a slightly below-average HP stat and neutral ATK, DEF, and EVD stats. However, she can lean towards being aggressive thanks to her unique passive, similar to Tsih. Whenever Mei has no cards in her hand, she will draw  Red & Blue, the most powerful stat-boosting gift card in the game, providing +1 to the ATK, DEF, and EVD stats as long as the card is held. This provides the player with completely positive stats and durability that is unequaled by rivaling attack characters such as Sora and Marc. Unsurprisingly, the player should try to get Red & Blue the earliest they can, to keep Mei as strong as possible for as long as possible. If the player is lucky, this can sometimes be accomplished by starting with a zero cost card they can play immediately, like  Flip Out. This need to zero out the hand also makes Mei one of the few characters who can directly benefit from  Scrambled Eve, as she will always get Red & Blue back after its activation. With a bit of luck, she can even draw the one sent back to the deck, providing her with two copies of the card. Once the player has the gift card, Mei will generally not have much difficulty defeating  Encounter panels and surviving  Boss panels, as her ATK will either be enough to defeat the opponent, or her DEF and EVD will protect her from both high and low rolls. As a result, depending on the player's performance, they can use Mei to fulfill either norma as she can fight well or defend herself and collect stars. Also, if the player has Red & Blue in their hand while Mei has her Hyper in hand, the player will have access to a powerful Hyper that can be used to punish players for coming near her.

The inherent disadvantage of Mei's kit is her reliance on  Red & Blue. Without the card, Mei is a weaker QP that should avoid battle, and if Mei is KO'd the player will lose the card. This means unlike most of the cast, the player will generally want to keep a very small hand at all times in order to get the card back should they lose it. However, this may not be possible, especially if the player is holding cards like  Sealed Guardian or  For the Future of the Toy Store which can be very hard to discard. This can also make it very hard to plan a powerful play for Mei, as the player must always plan to be able to empty their hand in a moment's notice if they must. Consequently, Red & Blue is also an inconvenience. Since it must always be held to reap the full benefits of Mei, the player will only really have 2 card slots to work with instead of 3. Likewise, if the player loses Red & Blue, Mei's Hyper also becomes substantially worse and will often need to be used just to remove it from the player's hand. In short, discarding Red & Blue will set the player back in the game and it may be quite hard to make a comeback after it is lost. Thus, while Mei can battle with the likes of Star Breaker the player should try to distance themselves from powerful bully characters when their hand is full to avoid losing Red & Blue.


As previously stated, Mei can potentially play for either wins or stars dependent on how well the player rolls and if they get her passive gift card quickly. If the player is lucky enough to get the gift, do well on  Encounter panels, and KO an opponent with her Hyper, then wins can be viable. If RNG is not on the player's side, however, her stats should support her well enough that the player can collect stars in peace and counter-attack well in response to opponents. Overall, Mei is used for star norma more often than not, but wins norma can sometimes be used for norma 2 and 3 during the course of the game.


+Balanced stats make for an adaptable playstyle
+Has two unique cards,  Red & Blue and  True White Christsmasher that make her quite powerful
+Opponent cards that cause the player to discard are often beneficial
+Red & Blue requirement for the stronger version of the Hyper makes it generally useless for opponents
+Hyper that damages people on the same panel discourages opponents from challenging her
-Heavily reliant on  Red & Blue
-Hard countered by  Gift Exchange
-Might be unable to rebound from difficult scenarios or reclaim stolen stars after losing  Red & Blue
-Having an expensive or high-level card in hand makes it very difficult to get Red & Blue
-Weak Hyper without Red & Blue
