Love of the Armored Daughter! Maiden Heart is Shaky Wobbling Urusei Yatsura : Season 1 Episode 156

Episode two of a two-episode Serial. Her armor now gone, a terrified Asuka runs away from Ataru, Shutaro, and even her own brother Tobimaro. It's also revealed why Asuka is in the armor; no male from the Mizunokoji clan is allowed to see their daughter until she turns 15. Shutaro, initially against the idea of the arranged marriage, is now all for it when he hears from Ataru that Asuka is cute, despite her being scary powerful due to 15 years in armor. Ryoko, however, plans to put a stop to the arranged marriage with a giant army and later an armored suit. The marriage is soon after called off.
