Ultraman Tiga: Heir to the Light

Six years after the Final Holy War, Da Gu and Lina have been living on Mars for four years. During that time, they have returned to Earth only once, to attend the handover ceremony between GUTS and Super GUTS. At the ceremony, every GUTS member except Captain Megumi retired. TPC then established Super GUTS, led by Captain Kibi Kosuke. Humanity has only just begun planning to build a second home on Mars, so Super GUTS has not yet appeared there.
