Ms Mari is revealed to be the "Key Person" that can save Kinnikuman.
Story[]
Mantaro Kinniku and his group sleep for the night at Gakincho House: the orphans and nuns together, Jacqueline and Ikemen Muscle together, Chaos Avenir and Mantaro together, and Rinko and Mari Nikaido together.[1] Rinko awakens to find Ms Mari absent, and goes downstairs to see breakfast is being served. The news shows Kinnikuman training with Terryman, but seemingly unaffected by his Demon Hourglass, and Kinnikuman wins their sparring match easily against their faux-opponents (with him accidentally injuring Mayumi Kinniku, who is dressed as Neptuneman).
Kinnikuman suddenly collapses, as the Demon Hourglass bursts through his chest once more. Ms Mari looks to the television screen, which causes the sands in the hourglass to slightly retreat, and Rinko notices this (especially as no other person was able to make the sands of the hourglass retreat). This causes her to believe Ms Mari is the "Key Person".[1]
