Tsuki Natsu

Tsuki Natsu is a Homo Aquarius, a sea serpent and human mix created by the Society of Concerned Scientists(or SOCS), gifted with light powers. She's a recruit in Catastrophe's Army who quickly worked her way up to being an elite soldier. The entire time, she hated Catastrophe.

Background
Tsuki grew up in a small fishing town known as Sapphire Cove, which is located in Southeastern Kyngdom, just a few miles northeast of Mer. She lived there until about the age of ten. At this time, she, her mother and her father had been in amostly-hidden cove.

One other person was there... Little did they know, this was a scientist working for SOCS. Later that day, they were kidnapped and brought to the SOCS headquarters. When her father refused to obey orders, he was executed on the spot.

Her mother was taken for experimentation. She was killed during expedimentation. Tsuki was first sent to the boarding school part of SOCS, where they trained young girls to fight and kill. However, SOCS discovered that her mother had light magic. They took Tsuki back to the lab to test  if she'd inherited her mother's abilities.

Tsuki had in fact obtained light magic. However, she didn't know she had magic, and so SOCS kept it a secret from her. They began experimenting on her. She became a Homo Aquarius.

A year later, and Tsuki escaped from SOCS. She traveled Kyngdom, searching for jobs. This was when she met Raven Shadows. She and Raven became good friends. But then Tsuki was forcefully drafted into Catastrophe's Army.

In-Story
Tsuki was introduced during the Power of Hoof chapter.

She arrived at Jokull. During the role call, she was one of two recruits that was discussed by General Grimm and General Caligo. The other was Ashzan Moksovinan, a forest elf from the Decoy Forest.

She was called forwards and discovered she had light magic, when a blinding blast of light suddenly appeared in her hands.
