[And yet that person's life would still revolve entirely around Pokemon.]

Uhuh. There's a guy you meet later, he basically thinks all of this stuff is abusin' Pokemon and that they all need to be set free, but really it's his dad who convinced him up that cause he made him grow up like all isolated from people and shit.

[A misunderstood antagonist who gets befriended by the well-meaning protag? Of course Rin would like a story like that.]
