Sally transmigrated to the world of heroes and demons. To a body of 320 y.o female elf. Being old is fine, elf is an eternal beauty. Being a main wife of hero's harem... well, hero is missing so it's fine. "Wtf, god, are you kidding me?" Now, the 20 y.o Sally is a mother of four. Oh, no! There is a soon to be born baby, so it's five. Roona, eldest, 15 y.o human girl. Argee and Arfeena, twins, 12 y.o half mermaid boy and girl. Rooga, fourth, 6 y.o half elf boy. Soon to be born baby of a demon princess... let's think about name later.
