Non Non Biyori, Kobayashi-san Chi no Maid Dragon Recommendations
Similar style of comedy focused on a cast of air heads of various degrees.
Introduces it's own Kanna in Renge who also becomes by far the best part of the show immediately.
Both are light, calming, funny, heartwarming and generally not cruel comedies. Main characters are cute and unforgettable, you will love them.
Both have the same slice of life happy feeling. Also having similar soundtracks and color pallets. Should also mention that Kanna is Renge's dragon doppelgänger.
