for the fire orb you have to be able to produce firewood, so get "use tools" at lvl 4 and produce firewood, once you made the first firewood stack, the orb will appear in the shop
a couple little suggestions: 1) get a better artwork, most of them are recognizable, but some are just too hard to see who they are; 2) use original names for characters, not everyone grew up in US and don't know the US names, while everyone with a little interest on animes knows the original name of the character, i.e. the sailor moon main character in the game is named "Moon", in italy (where i live) it's "Bunny" (that's the translation of the original name "Usagi"), while the italian of "moon", "luna", is the name of her cat... that would make it simplier to find the right name of the characters
It would be nice if exp from killing monters carry on to the next lvl, I mean: i did the reborn thing, i killed a monster that gave me 6k+ exp at lvl 1, and i leveled to lvl 2, when the requisites for lvl 1 are like 100 exp, so I lost all the other exp points
