Giji Harem

Both feature playful teasing and fun games between the main characters, slow-burn romantic development, and lighthearted interactions 

- Kotori (Amaama to Inazuma) and Rin (Giji Harem) have pretty similar personalities and the story involves how they get along with a man who has the same interest as them. - They both voiced by Saori Hayami, so if you like Yukino from Oregairu, and looking for a female character that looks like her, you can try both anime! - The overall atmosphere of the shows are very cute and heartwarming. Main difference is, Amaama to Inazuma focused more on bonds between a father and daughter, while Giji Harem, as the title says, focused on harem (in a unique way!) 

Both animes follow a couple from their first meeting at school to the future. The boys and girls in both animes are simple and hardworking. The couples support each other's dreams and strive to live a trouble-free life. 

-> Rin and Kozue both could switch emotions/personalities. The difference is that Rin got her ability through acting skills, while Kozue got her ability through a string of traumatic events. -> Both genres are comedy and romance. However, Giji Harem’s setting is mostly at school, and Mahoraba’s is mainly at the boarding home (like Toradora or Pet Girl of Sakurasou stuff)
