The Ideal Sponger Life manga volume 13 features story by Tsunehiko Watanabe and art by Neko Hinotsuki.

When Zenjiro came to the Kingdom of Capua, he hoped for a laid-back sponger's lifestyle, but now he'll do anything to protect his wife and children. With a new baby on the way, he's traveled abroad to the Twin Kingdoms, hoping to secure a magical healer to help with childbirth. Yet no sooner did he arrive than the king declared his intent to abdicate the throne!

A royal succession is never a simple affair, but Zenjiro is at risk of being used as a pawn in the intrigues of foreign royalty. Hidden truths lurk behind public facades in a nation where the ancient traditions of the desert struggle against newfound feudal customs. When a shocking revelation threatens to draw the Kingdom of Capua even further into local affairs, Zenjiro's not about to take it lying down!
