Lulu

Lulu is the youngest member of the Schiff and the only one to survive after their fight against Diva ends. She has purple hair and emerald green eyes. She carries a battle axe as her weapon.

Plot
After breaking out of their cells in Khilbet, the Schiff, led by Moses, set out in search of Saya to obtain her blood, which according to a dying scientist is the only thing that can stop the Thorn's effect. However, they come to know that they were misled after a failed attempt to save Irene with Saya's blood. It's Diva's blood they require, not Saya's.

Henceforth, Lulu develops a liking to Saya. She seeks Saya out in times of trouble for aid. She also hangs around Saya for company, much to Karman's disdain. After realizing that James manipulated him into thinking that he could save Karman from the Thorn, Moses decides to spend his final moments with his friend, leaving their weapons to Kai, telling him to pass them on to Lulu for her to remember them by. Kai does as requested and gives Lulu the weapons back at the apartment the Red Shield members were staying at. Being the only Schiff alive and not having developed the Thorn yet, Lulu is offered to stay with Red Shield where she fights alongside Saya and the others. After the final battle is over, Lulu also goes to Okinawa where we hear from David and Lewis that Julia found a way to extend her lifespan after finding a cure for the Thorn.
