Tenshi ni Narumon! EP11 - It's Suddenly Time to Say Goodbye

A comet is coming and it has got Mikael worried for Noelle. Yuusuke and Natsumi are chosen to be the class representatives on the committee for the school's Durian festival to celebrate the comet (that looks like a durian fruit). Yuusuke has a chat with Kai, learning about the relationship between Kai, Natsumi, and Natsumi's dead brother Fuyuki. Kai was always in love with Natsumi but she only ever saw him as Fuyuki's friend, then when Fuyuki died she started to hang around Kai more (likely using him as a replacement for Fuyuki). Mikael speaks to Yuusuke, telling him to not let Noelle out of his sight and Yuusuke goes to find her. She's with Lucca at the school's clock tower, they were going to use the comets power to help Noelle fly, but the clock started to wing backwards, catching the hose attached to Noelle's mechanical wings and lifting her into the air. Yuusuke arrives just then and helps get her down before running up the clock tower to see what was happening. When he gets there, he finds Natsumi, but she's become a child again!
