The Ideal Sponger Life: Volume 13 (Light Novel) oleh Tsunehiko Watanabe

After a long journey, Zenjirou has finally arrived in Uppasala, Freya’s homeland. Immediately upon his arrival, he meets with King Gustav and various movers and shakers in the country. In order to finalize the trade deal between their countries, Zenjirou asks the king for his daughter’s hand.

Naturally, many of those present are unwilling to give up their first princess—particularly to a prince consort—but the first prince, Eric, is especially hostile. His warrior spirit and aggressive personality lead him to absolutely refuse to allow someone who has not even passed the Rite of Age to marry his little sister.

To attain the right to truly propose, Zenjirou finds himself facing a complex situation—one in which he will need to prove himself a man by the norms of a somewhat militaristic nation.
