Mahoutsukai no Yome, Somali to Mori no Kamisama Recommendations
Both surround themselves around a special human who deserves and needs love and support. Both are in fantasy worlds where supernatural creatures abound. Both are super sweet and heartwarming. And both are based on relationships that are pure of heart.
A young and vulnerable girl by fate meets a very old non-human whom acts as her guardian.
The main characters in both series are kinda similar and their relationship reminds of each other. In both series there is the older male character who takes care of the young female character.
In Mahoutsukai no Yome their relationship is more romantic as in Somali to Mori no Kamisama it´s more like daughter and father kind of relatioship.
Another fantasy series with BDE (big dad energy). I really felt the similarities where the unfeeling father figure would touch their chest and ask the human to explain the feelings they are currently feeling.
they both have the same fantasy feel and they're both about a big non-human dude and a human girl (one's about romance and the other not tho)
These series bear closely resembling themes being that they both share similar MC dynamics featuring a young human girl and a drastically older creature lacking in their conception of humans interating with a vibrant fantasy setting whilst going about their lives/journey.
