Marito Kaizuka

Marito Kaizuka (界塚 マリト, Kaizuka Marito) was a former soldier who became a doctor. With his wife Yuki Kaizuka he ran the Kaizuka Medical Clinic, and during the war against the Vers Empire he supported his brother-in-law Inaho Kaizuka.

History

Marito Kaizuka left the military for medicine, then returned to the war as an adviser and doctor when the Vers Empire invaded Earth.

Civilian practice

Marito had left military service for a career in medicine, and he ran a small clinic with his wife.

The invasion

When the Vers Empire invaded Earth, his military background made him a valuable adviser to the local defence forces. He recognised Inaho’s ability and supported the decision to join the fight, despite his wife’s concerns.

During the invasion he gave medical support and tactical advice to the Earth Forces. His experience as a soldier let him see the strain on the younger pilots, and he stood between the military command and the civilian volunteers.

Later medical service

Marito went on supporting the war through his practice, treating wounded soldiers and civilians alike. His tie to Inaho deepened as the fighting escalated, though he worried about the toll it took on the young pilot.

Personality

Marito was calmly professional, and quietly strong. As a former soldier he understood combat, and he had chosen to heal rather than fight. The clinic was his commitment to preserving life in the face of the war’s destruction.

He was a father figure to Inaho, offering guidance without pressing it. He accepted Inaho’s place in the war because he knew that some battles had to be fought, even at great personal cost.

Relationships

  • Inaho Kaizuka: His brother-in-law, and the person he felt most responsible for protecting. He recognised Inaho’s abilities and supported his decisions, including the dangerous ones.
  • Yuki Kaizuka: His wife, and Inaho’s sister. Together they kept a stable home that grounded Inaho amid the war.
