Personal Commentary about the guide + boss fight
I am sure there have been many other people who made this sort of guide, but I am making one myself as most other guides simply skip certain parts, hence confusing players who are trying to reach this boss themselves for the first time.

That is why I have provided a clear cut guide that includes

- RED/WHITE text importance highlight
- A text when a tape does not have an effect on the boss fight
- When a dialogue will need to get spammed
- A clear cut 100% included guide that has every factor you will need to account for when doing this

I do recommend trying to fight this boss only after having gotten accustom to playing this game and having finished the story

This secret boss is very dialogue sensitive so you have to pick the dialogue options VERY carefully.

(Note if a character dialogue is not mentioned, then it simply bares no effect on the final outcome of if you will get this boss fight or not)

Good luck!
Step by Step details on how to reach the secret Katana Zero boss
If you see "complete" written next to its correlating tape, then the tape and what happens in it will bare no effect on the final outcome of if you get the opportunity to fight the final boss or not.
