It was another typical day at school until Youzan (Haru's older brother) showed up. Youzan talked to Shizuku and explained that Haru has been a troublemaker and that their strict father wants him to return home. But since Haru has returned to school, because of Shizuku, Youzan was going to convince their father to let the younger sibling keep living with his cousin Mitsuyoshi. Haru and Shizuku seem to have grown closer, but Chizuru's gratitude towards Haru appears menacing for Shizuku.
In episode 5 of My Little Monster we learned a bit more about Haru's troubled past. I was glad to see Haru and Shizuku grow closer, but Chizuru's presence seems a bit tacked on to produce more drama. Also, I like Shizuku and Haru a lot, but I want to see more of Natsume, Sasayan and even Yamaguchi. My Little Monster has been enjoyable so far, but I hope the producers do not add too many elements (e.g. Chizuru) to the table and ruin the show. This episode gets a 8 out of 10.
