Affection can also be increased by giving the characters sandwiches that can be purchased at Duel Academy ' s card shop . Everyone has different tastes , though all seven characters love the Golden Eggwich . Affection is measured via a heart meter . Once six hearts are obtained , the character will offer to become your partner .

One may attempt to get as many characters to six hearts as possible , and it is possible to get all seven to full before ending part one . Each Sunday , Tag Duels are held at the Academy ' s Duel field . Of the seven characters , the one you have the best affection level with will be you partner for those Duels .
