Lilith

Lilith is the final main member of The Legion, Shade's Flock

Personality
She's a bit of an antisocial person. She is notable for being a Chūnibyō or having High School Second Year Syndrome. Meaning that she believes that she's supernatural. She always calls her self Lilli the Demon and could be easily annoyed when somebody calls her Lilith. She's friends with Myusix since they both attdended the same Kindergarten. She's very unlucky and could be teased.

Her bad luck
Her bad luck can cause to bad things, like if they go on a trip, it's bound to rain. That's how she got the name Lilli. I forgot to mention that nearby the end of each month, she'll always get sick. She went to the Lunar Lands Archapelago with Myusix but due to her bad luck, she went on a seperate raft.
