Also, Ralsei, what do you mean you liked it? Aren't you supposed to like Kris?

We got Flowery in Chapter 5. So, does Flowy exist?

As you can see, I made it to Phase 3. This is my 8th attempt. From what I can tell, it's possible to No-Hit Phase 2. So, I believe this is possible.

Genuine question because I'm playing Chapter 5 blind, so I don't know anything. I may as well be stupid for thinking this, but they don't seem like the secret boss. Ralsei literally said that the key might be used for something else. This just seems like a secret fight. Also, the fight doesn't feel like a secret boss either. It doesn't feel difficult enough nor does the vibe feel like it fits the secret boss. Though, this is my first attempt and I'm getting terribly destroyed.
