So, after visiting Charmander's house, you go outside for some fresh air, until you sound someone yelling: "HIYA, HA" coming from the backyard, so you investigate, only to see someone with crimson red armor... a horse tail? and a crimson sword, they seem to be... sword fighting with someone, until she notices you

"Ay, human, the hell you doin here?!"

you explain

"Oh, you're a friend of Charmander, well then, welcome."
