S1·E22 Welcome Back, Dad! The Hoshina Family's Tanabata

On Tanabata, which also turns out to be Lala's birthday, Hikaru's father Yoichi returns home from his research on aliens and cryptids abroad. As the family prepares a barbecue party to celebrate all three occasions, Hikaru explains how she encouraged Yoichi to go overseas and pursue his dreams, much to the dismay of his father Harukichi, who felt he was just abandoning his family. Just then, Harukichi, who blames himself for not raising Yoichi properly, is turned into a Notray by Tenjou, but is saved by Yuni. Afterwards, Yoichi and Harukichi manage to patch things up with each other before celebrating Tanabata with their family.
