Sumomomo Momomo: Chijou Saikyou no Yome

Episode 22

With Kōshi and Momoko poisoned, they have to still battle Tenga Koganei in order to get the antidote, but the sun is close to setting, which means death for Kōshi and Momoko. Upon entering battle, Momoko finds that Tenga is much more powerful than she expected and before long the battle is all but over. When Momoko cannot fight any longer, Tenga gives the antidote to Kōshi, though there is only enough for one person. Right before the sun sets, Kōshi gives Momoko the antidote, and after she awakens to find Kōshi dead, unleashes her ultimate fury on Tenga, and wins the battle. Afterwards, it is found that Kōshi was miraculously healed due to a martial arts technique his mother had performed on him when he was young. Everyone goes back to living their "normal" lives.
