The finding distinguishes an actual story-based recruitment event from methods that merely force a character into the party. Power Up Gaming reports that Lilith can join through an in-game sequence rather than solely through a cheat, glitch or externally modified version of the game.
The discovery was documented by Japanese player azekura, according to Power Up Gaming. The reported route includes avoiding items taken from civilian homes, following the party’s destination instructions and speaking to Lilith exactly once during an earlier visit. The outlet also notes that the tested route may not include every requirement.
A later part of the reported sequence involves obtaining a Silver Ladle during a fish-buying errand, returning home and completing Philia’s reunion scene. Speaking to Lilith outside afterward allows her to join, Power Up Gaming reports. These specific steps come from that account rather than from the independently corroborated core finding.
The route also appears to work beyond the Japanese release. Power Up Gaming reports that English-speaking players demonstrated the recruitment scene in the North American version, including confirmation that it works on the NTSC-U release.
The Japanese version has an edition-related complication in the reported guide: recruitment works in the first printing, but a later story event fails to trigger. According to Power Up Gaming, loading the save with the later BEST re-release allows the story to continue. The available evidence does not establish that the route works in every edition, and the complete set of requirements remains unresolved.
