Hyouka, HaruChika: Haruta to Chika wa Seishun suru Recommendations
The pace is quite similar, both animes are about high school students resolving mysteries, and one of them is quite smart.
- Both have a mystery + solve the mystery
- Both about a group of student + about school
- Both include a club activities
- Both main heroine is full of energy lol
- Both main hero(?) who solve the mystery
- Romance not hinted between the main chara
Both are animes happening in high school with little mysteries to solve and some slice of life moments.
You could say Haruchika is a rather immature (ie. uneven, thus far) combination of BOTH Hyouka and Hibike! Euphonium: mystery-solving character drama involving a brass band club.
Takes place in school too, it's about a club too actually. Very similar to Hyouka, but I gotta say Hyouka has a bit more intense and adult and serious aura than HaruChika.
