Kapone was able to educate her daughter, Sonata, to be a proper lady like herself in the old days. However, she is still serious about combat and clueless when it comes to raising men. While she raised the OSX-kuns, her attitude toward them was summed up by her words: "If you train them, they won't die."^{[Challenged]ⓘ}

Sonata is called "nee-san" (姐さん, older sister), and Kurou is referred to as "anija" (兄者, older brother) While the superior among the Tora brothers is also called "anija," they might add a modifier like "○○ anija" when addressing someone to avoid confusion^{[Challenged]ⓘ}.

They call Windows Family "Madoshu" (窓衆, window people) and they particularly did not get along and has a sense of rivalry, despite their minimal interactions. They lack individual characterization and are not well-organized or intelligent, since all five of them always appear together, they can cause sweltering heat around them, thus making them not get along with others^{[Challenged]ⓘ}.

The Tora Brothers often deliver their lines collectively, with each brother speaking one word at a time, and they conclude with a spirited shout of "Nee-san, MoeMoe ja!!" (姐さん、MoeMoeじゃー！！) to deliver the punchline. This pattern remained consistent even with the introduction of Yukihyo, which was expected to lead but did not^{[Challenged]ⓘ}.

The Tora Brothers initially had a human-like appearance like Reobo.
