Could've made this 2 days shorter, just dun remember how.

Note: The events are not required to unlocked the scene, only the skill. For NG+, you do not have to go through the trouble finding the event again, just use the skill on the boss.

Mistake on my part, I believe NG+ is not required.

Hscene for chapter 3:

Your main goal is for Ayumu to gain skill Independent Heart and use it at least once in the final battle with the shrine maidens.

Hscene for Chapter 2:

Obtain skill Sister Blade and use it on final battle of that chapter.

Hscene for Chapter 4:

Gain Absolute Horizon and use on final battle of Chapter 4.

In short, try to meet the requirements/events in order for Ayumu to gain special skill on each chapter and use it at the main battle.

I got on 2nd play. Just aim for new game+ I suppose.
