Tanaka commands the Dancouga Nova team from the covert Dragon's Hive base, assigning missions and fielding pilots' questions about their objectives and the machine's origins. His knowledge of the project surpasses what he reveals, indicating access to classified layers of the organization's true goals. Despite this guarded approach, he consistently prioritizes the pilots' safety and combat readiness.

Frequent battle emergencies abruptly cut short his briefings, leaving the team with fragmented operational context and obscured truths about their missions. As the original sole conduit to the enigmatic overall commander Mister F.S., Tanaka focuses exclusively on strategic oversight—never engaging directly in combat—while balancing urgent threats against the pilots' need for clarity.
