"For the past three days, there have been two Rio Futabas." After successfully breaking the time loop that he and Koga were trapped in, Sakuta's threshold for what qualifies as "odd" was higher than most. So seeing his friend Futaba in a net cafe late at night should have been downright unremarkable-if he wasn't already on the phone with another Futaba...The ever-logical second-year has a doppelgänger, and neither one can (or will) explain what's caused this sudden case of Adolescence Syndrome. With one of the Futabas staying at his place, Sakuta will have to work fast in order to solve this. After all, who knows what could happen if the two doppelgängers meet?"
"Today...is yesterday?" Sakuta may have cured Mai's Adolescence Syndrome in the nick of time, but now he faces a no-less-harrowing task: convincing her to officially date him. After managing to win that round of verbal fencing, he gets some well-deserved rest...only to wake up "yesterday," with all his progress reset. This inexplicable phenomenon seems to be caused by Tomoe Koga-the self-righteous yet self-conscious schoolgirl who offered up her own butt to be kicked after mistakenly assaulting Sakuta's-and the only cure is to...pretend to be her boyfriend?!
Saki's never been a big fan of mahjong. A lifetime of being forced to play with family at holidays (and losing her money as a consequence...) has left a foul taste for the game in her mouth. When she's convinced, though, to play a game with her classmates, she discovers that not only has fending off her family left her with an uncanny ability for the game but, more surprisingly, that it can even be fun!
Is this revelation enough to cleanse Saki's distaste for the game? Can her classmates convince her to join their club, or is there just too much baggage to make it worth her while?
If you're looking for the number one mahjong manga out there, you've found it!
