When the trading company office worker Ichimiya Shingo wakes up from his nap he finds himself in an unfamiliar world in the body of a five-year-old boy, Wendelin (Well), from the noble Baumeister family. Though he's confused at his new surroundings, he's reassured to learn that he won't have to worry about food as a noble's son, but then he learns that he's actually the eighth son of a poor noble family in remote lands.
I'm the eighth son of a poor noble
 family that lives out in the sticks.
.أنا الابن الثّامن لعائلةٍ نبيلة فقيرة تعيش في الرّيف
Der achte Sohn einer armen
Adelsfamilie vom Arsch der Welt.
Soy el octavo hijo de una familia
de nobles pobres de la periferia.
Soy el octavo hijo de una familia
de nobles pobres de la periferia.
Je suis le huitième fils de nobles
sans le sou paumés à Perpète-les-oies.
Sono l'ottavo figlio di una famiglia nobile, 
ma povera, che vive in un posto sperduto.
Sou o oitavo filho de uma família
nobre e pobre que vive nos cafundós.
И я — восьмой сын бедной знати,
обитающей в глуши.
