by family focused in this situation, I want something sibling focused instead of parent child.
not purely sibling but more family oriented (as in whole family get isekai'd)...i like it so much so maybe you can try this out : Tanaka Family Reincarnates => https://www.mangago.zone/read-manga/tanaka_family_reincarnates/
I was wondering if people know stories similar to "I’m the Main Character’s Little Sister".
