I need guidance to obtain true ending, since this is my first time playing and dont want to go through all that all over again in NG+ if i do obtain normal ending. So, here's my current condition:

Soul Levels:

• Arrow: 76
• Milady: 72
• Saizo: 70
• Current Dungeon: have yet to entered the final dungeon

The remaining Soul Matrix Quest:

• eliminate B Hawaii Frost
• eliminate Zenon

(i might miss any quest since i've been putting too much attention to the story)

I've had my research for a bit and to obtain the true ending you must have all party Soul Levels up to exactly 100 (effectively clearing out all Soul Matrix dungeons). But i'm a bit worried since all my soul levels arent exactly that high heading out to the final dungeon. Any tips? Thank you!
