So it seems that when you enter the Shop (or is it specifically the Spirit Shop?), one of a few vendors will assist you. Here are the five vendors:
- Sheldon
- Anna
- Funky Kong
- Timmy & Tommy
- Beedle
Also, there seem to be 16 teachers/coaches, and these teachers can teach your Spirit a "Style", with a unique style for each teacher. I have no idea what these styles do. I haven't been able to find the names for these except for two, so I guessed some based on what they say. Here they are in the order they're listed.
- Rodin? - Demon Style (nothing notable about their speech, but Demon Style sounds related to Bayonetta)
- Cap'n Cuttlefish - Land Style! (name was listed)
- Peppy Hare - Air Style (had no clue until he said "Never give up! Trust your instincts!")
- Copper & Booker - Brick-Wall Style! (name was listed)
- Daruk? - Boulder Style (very energetic, yells "HOT!", talks about rollin' and how the spirit is "part of the family")
- ??? - Big-Bee Style (talks in a somewhat seductive way, also says things like "Oh my...", "Ah, marvelous.", "What a pity...", almost definitely a female with big b's (Camilla?))
- ??? - Runner Style (says "That's the power of science!", also says "I've been waiting." when you enter)
- ??? - Gravity Style (a physicist, mentions Newton, calls the training an expirement)
- ??? - ??? Style (seems like an animal or Pokémon that talks by yelling, doesn't mention the style, yells are like "Gy-aon!", "Gwoooh! Guruoo…", "GlOOYA BLEESHK!", lots of sounds beginning with G except for a "ROAR")
- Wii Fit Trainer - Lightweight Style ("Who's ready to get fit? Wii are!")
- Riki - Strategist Style! (says his name)
- ??? - Equipment Style (says "Oh ho ho ho ho!")
- Zangief - Overthrow Style (definitely Russian since he says "Khoroshiy!", talks about strong arms and piledrivers)
- Kat and Ana - Ninja Style (say their names)
- Slowpoke - ??? Style (doesn't say anything, text is in second person)
