Haruna Nana: Haruna-san Chi no 7-nin no Oniichan

The Haruna family is famous for being poor, with eight siblings, including the youngest sister, Ran, and seven older brothers who love their younger sister. The daily dinner table is a little lonely with only a few side dishes, but the older brothers do their best to make sure that Ran is their "top priority"!! Everyone is friendly, and every day is lively. (Source: Kadokawa, translated)
