Notes

Any secret that's acquired, besides Lux, Romina's new outfit, and Camo Bilvine stays acquired across all playthroughs. Route split flags are usually permanently-set as "on", although it's a little odd when it comes to Yllbora. If a secret requirement is to "defeat X with Y", that flag does not carry over and has to be done every playthrough you're attempting to get that character, until you get them. The skillparts acquired from secret characters are one-time only. To get more of those skillparts, you need to do DLC stages (Puzzle Robo/Campaign Map). Killcount requirements are based on the character's base amount of kills (however, 999 has no effect on secrets) displayed on the status screen either in the intermission or the stage where they join. So the killcount requirement has to be made within the playthrough, and none of the kills made carry over; everyone's killcount for secrets starts at "zero" every playthrough.

For instance, Shouko requires Kazuki to have 100 kills, which means he needs to make 100 kills within that playthrough by the deadline, starting in stage 13 (him needing to defeat the Sphinx Festum in the prologue does not add +1 to his killcount for the purpose of Shouko; it's only step 1 for the whole thing). Getting a game over keeps the number defeated by the required character in the "flag memory", meaning it's entirely-possible to grind kills for secrets. However, if that character's first appearance is in the stage and they make kills, and then you game over, it won't count. For anyone whose kill requirement involves 2 or more characters, it's not known if zero is a valid amount for one character to have as long as at least one other person meets the requirement.
