Natalie's interesting; choose her if you like the magic systems in games and are drawn to characters like Blue or Judy starting out. Her boss is tougher than Shiki's, I tried to kill all parts simultaneously while having Phoenix up as long as possible, but that ended up not mattering. Since this is my second time fighting it, it went a lot smoother, but this is scary as hell. Especially the end where you just have to hang the hell on.
One thing to note: if you die on this boss, it will delete various aspects of the game such as the light, atmosphere, sound, until it just forcequits the game Undertale style. I struggled enough my first tries at this thing that I saw that a lot, believe me.
