@Varler I feel like there's about a billion CCG type dealies now that are like crosses between Yu-gi-oh, Pokemon, and MTG. You know those character creation tools in some games where it's like a triangle, and you pull the slider around between the three points to change like body shape or something? That's how people make new card games nowadays. Just slide the thing around and decide how many elements to use from each that aren't already in the others.
Now go back to the chapter with adult Tsubasa and imagine her with those expressions.
Phew, she's going to break some hearts when she gets older. xD
@Dragonbolt03 Subjectively speaking, that's a spoiler....
It's so hard to recommend that manga because by recommending it you automatically spoil it by telling someone the reason you recommend it. Cuz then it's too obvious.
