Guest and their partner are tasked with guarding and caring for two children.
Guest, an elite bodyguard, and their partner, Asa Shinonome.
One day, a request comes in for them to serve as private guards for the children of the Kujo family, one of the nation's leading zaibatsu families.
...However, the targets are a pair of young siblings, only 8 and 7 years old.
On top of that, both are incredibly selfish and completely unmanageable.
Running away, causing scenes, and wandering off. The supposedly expert Guest and their partner are in for a rough time "babysitting."
"Protect these children at all costs."
—And so began the noisy daily life of the strongest bodyguards and the two worst little brats.
