Not always. Even on neutral/peace you need a low sus-Score with nauxus. 3 or less.
If you wanna know how to get the very best neutral ending, making Axel, Thane and Nauxus happy: https://itch.io/t/1392488/good-ending
look under: In my opinion the "BEST good/neutral ending":
To get all scenes you need to play the game at least twice: 1x neutral/ peace Ending to get both Nauxus ( Sus =<3) and Thane (automatic on neutral) + 1x Bull / Axel Route (kill Nauxus) to ask Axel for S**.
