I feel like, if possible, the title shouls specifically be formatted as normal_npc (or however it is in the game's code) like other names taken from the code (Eg: shadow_mantle_enemy, gacharoom_unknown)
The move has happened, it is now Normal NPC. I'm not really sure why we left that character in limbo anyways, I think there was some indecisiveness between "Normal NPC" sounding unconventional, or taking "Bird" as an alternative for an internal name.
