The OTPimp Challenge is an Exchange of Alternative pairs! It's the other pair that your friends refuse to listen to you about or read about! You know, that crack pair you've been keeping in your pocket, hoping that one day, someone will love Horio and Arai as much as you do!

Or in the case of this community, to write all those WEIRD Marui pairings you love and adore!
