Something like stuffing a pot with poisonous insects to breed the one with the strongest venom...A sudden chill...!That really is great...Gensokyo is quite interesting after all, isn't it...Indeed...That tiny nook of a Far Eastern island nation is a real melting pot of various gods and youkai.Wriggling about, mutually growing in power...Even in this case, it's because they make full use of their great power that they can cast such a grand sorcery.........I see.Wasn't there a spell like that in your country?What was it again?
