People have discussed the possibility of a 100% speedrun. The main obstacle in the way for most runners is Secret 5.

I've proposed an idea to a few people and have had positive responses overall. Would "All Bosses" be a decent category idea?

1. Flandre Scarlet
2. Shine & Bright
3. The Guy 4a. The Four Devas 4b. Next Stage (Influka) 5a. LunarMagic 5b. Cyber 5c. Influka Area
4. Kamilia 1s/2s/3s/4s. - Destination/Crimson/Nue/Gravity Man

I don't know how the run would look, or if it would be fun to play, but it's an idea.
