Damn, only a pokemon meta-gamer would be able to follow this conversation.
Basically, EVs are the part of the stats that a Pokemon gets with training (it also works in the Touhoumons), and IV is the part that makes each Pokemon of a specie different from each other. Basically, Koishi is meaning that Reimu has no training at all (very low EV), but that she is exceptional (high IV) among her specie that is already very strong itself (high species-based base stats).
To make it short: Koishi is just claiming that Reimu is a goddamn slacker who relies on her natural ability and who never trains. She's just a prodige, basically, and we all know it.
Reimu. Don't you agree that you have an image that you have a low EV value, yet possess incredible strength hailing from high species-based base stats and high IV values? Pokemon reference:
EV: Effort Value
IV: individual ValueReimu. In your case, you should be considered a miko rather than a human.
That alone will make your special ability amazing.600 base stats and max IVs?
What's that? A hack?No way.
If anything,By the way, why this so suddenly?Mashing the B ButtonWell. It's nothing really.since I'm a human and you're a youkai, your base stats have to be higher than mine.I wondered if this current Marisa can reset her EVs.Don't you think that she'll become horrifying if she turns into a macho physical sweeper when she turns back to normal...?
