Luxury Nighthollow's Links
Over the course of DRcade2, Lux became surprisingly close to Hazel, providing him the ability to speak about his worries. They care about him a lot, and even are blinded temporarily by their own feelings when approaching the mystery of who murdered Hazel in the game.
Post-game, Lux still tries to keep in touch with him, though given the fact that he doesn't remember the game's events, is taking their friendship slowly.
At first, Lux is an annoyance to Hazel -- but when his usually morbid humor doesn't scare Lux off, he's taken such off guard that he starts opening up to them.
By the time that the Fall Arc starts in DRcade2, he sees Lux as one of his very few, but very close, friends, and even allows Lux to proclaim themself as his 'wingman' when discussing his feelings towards his crush. (it's still cheesy though, he'll say.)
Unfortunately, however, Hazel loses his memories some time after, bringing their friendship back to square one. Still, there are times where, during especially silly banters between the two, it feels all too familiar to him...
Lux meets Michi through DRcade2 as Obai and, being someone that Fulvio - or Hazel - loves and cares for, Lux by extension cares for Michi as well. Though there was a moment where she genuinely thought Michi used Hazel's affections to kill him, when she realizes that Michi was looking for a way to die, she makes sure to make it clear that Hazel would want him to live.
Post-game, though their interactions are often small, she checks in on him and Hazel to see how the two of them are doing.
