Stories about regular girls being swept up in an unknown and vast world of magic and being guided by a mature and caring expert. While there is an overarching story relating to a greater magical antagonist, much of the narrative is about the quaint day to day discoveries of this newfound world.

Both stories follow long lived beings who lives among humanity and how the memories of their companions speak to the extended shelf life of the human experience. There are action and fantasy elements in both mangas but it's the quaint passage of time that ties all the stories together.

Grand existential adventure action manga set in medieval times that speaks to the human condition with strong interpersonal relationships. Vinland Saga is 100% more violent though.

Kids on the Slope arguably has better musical performances and a more complex love web to boot. It's not as MC focused or melodramatic as Your Lie in April, so it's a nice choice for people who are looking for another music orientated anime that is similar enough for those fans longing for that sense of nostalgia but different enough so that it doesn't feel like you're rewatching Your Lie in April. For those who like good music and awkward teenage angst.
