Dina

Dina (ダイナ) was an escapee from Glory Bell, and a childhood friend of Mister and Lucas. She was killed by Leuvis when she and her friends ventured into Goldy Pond.

History
Dina grew up in Glory Bell as an orphan, alongside Lucas, Mister, and countless other children. At some point during her time in the orphanage, Mister brought forward the idea of escaping (presumably after finding out the true intentions of the farms). From there, she escaped with the other children and Mister and Lucas. It's assumed she lived in the shelter at B06-32 for a bit, as some of the other children often had tea-parties while staying there. Once arriving, the children decided to all head out to Goldy Pond at some point, where they were ambushed by Leuvis and the other poachers, where a majority of their group was killed with the exception of Mister, who later resided in the B06-32 shelter and Lucas who begun living in the windmill

Cuvitidala Arc
As Mister died in the explosion, he woke up in the afterlife, surrounded by all the friends he had once lost. Dina walked up to him and hugged him warmly, Mister apologized for not being able to live on longer. Dina interrupted him and denied what he said. Dina continued to hug Mister as the latter cried in her arms.

Appearance
Dina sports a dark headbang to go along with her light hair and long bangs. In all clothing she's seen wearing, she normally wears the uniform all farm children wear, even into her teenage years; a button-up white shirt with a white pleated skirt to go along with

Personality
Not much is known about Dina, but it can be assumed she's very empathetic, as upon meeting Mister again in the afterlife, she greets him with kind words and open arms.

Mister
Not much is known about their relationship, but it's assumed they were very close in childhood up until her death at Goldy Pond. Mister is hinted at having a small crush on her when they were children, staring at her longingly until Lucas teases him supposedly. At Goldy Pond, Mister is seen holding Dina as she dies or struggles to stay alive after receiving heavy wounds.

Lucas
Not much is known about Lucas and Dina's relationship as children, but it is assumed they were close as children; with Lucas being a close friend of Mister's, it can be assumed Dina and Lucas have most likely interacted once or twice in the past due to their shared friendship with Mister
