His little brother was a lazy bum with an atrocious personality who loved spending money. If he lost the family's protection, there was no telling when someone might get him killed out there. His little sister was adorable and perfect, but far too innocent. Without the Doma Family's protection, she might be lured away by bad people...
For example, Sogo—cough, cough!
Whenever he thought of that, Taihei Doma would shake his head wildly. How could he suspect his own little brother and sister like that? He must have been seeing things that day, which was why he had mistaken his adorable little sister for giving off the aura of a lazy bum. Right, he had definitely been seeing things. No matter how unreliable Sogo was, he couldn't possibly turn Umaru into a lazy bum, could he?
Heh. Hehehe...
Wait a second, it wasn't impossible! Maybe Sogo had not deliberately led Umaru astray, but little sisters grew up watching their Onii-chan's back! If Sogo set a bad example, then with Umaru's innocent nature, she might imitate him. Being innocent was bad enough—what if she became as lazy as Sogo too!?
Whether it was his little brother or little sister, if either of them lost the family's protection, they would surely live miserable lives! Therefore, the Doma Family absolutely could not fall! For Sogo and Umaru's sake—as a perverted brother-con and sister-con, Taihei's blood boiled.
There was no helping it. Sogo was already hopeless. If the Doma Family were handed over to him, then given his laziness and prodigal spending, the Doma Family might disappear in the blink of an eye. Umaru, meanwhile, was far too innocent. Besides, as her Onii-chan, how could Taihei possibly let his little sister step forward?
Thus, the responsibility of shouldering the Doma Family had fallen upon
