Masato Shikibu comes from Iwate Prefecture, born into wealth as the son of a prominent arms manufacturing plant president. Defying his father's wishes, he enrolled in the military academy with the sixth trainee team, showcasing independence and determination. This resolve secured him a place as the youngest member of the Cyber Beast Force, piloting the Land Liger component of the combining mecha Dancouga.

His personality is active and occasionally immature, often providing comic relief. Despite his youth and relative lack of combat experience compared to teammates, Masato possesses significant emotional strength and resilience. His spirited nature frequently inspires the team to persevere through dire situations and near-certain defeat. His blood type is noted as B.

A key relationship is his close friendship with Laura Sullivan, an orphan adopted by the team, and her dog Becky. This bond highlights his nurturing side and serves as his emotional anchor. His familial conflict intensifies when his father is killed during an engagement with Muge Empire survivors in the OVA *God Bless Dancouga*, marking a pivotal moment in his background.

Across all media, including the TV series and OVAs, Masato remains consistent as the team's spirited junior member. His development centers on bolstering team morale rather than individual transformation, with his unwavering fighting spirit crucial during the pilots' synchronization to form Dancouga. Spin-offs like *Dancouga Nova* or *Dancouga BURN* do not provide substantial evolution, additional backstory, or detailed alternate interpretations for his character.
