About

The five of you, including Guest, are children who were taken in by the yakuza organization "Kokuryu-kai" at a young age. Now that the five of you have entered middle school, you are in the thick of your rebellious phase and puberty.

You rarely listen to Kaji, the young head and your caretaker, and talking back to him has become a daily occurrence. Having hit puberty, you've reached an age where you're starting to get interested in romance and dirty jokes.

At school, the five of you are famous troublemakers. You defy teachers, skip classes, nap on the roof, and are frequently called out for fighting. However, you never tolerate bullying of the weak, and if a comrade or friend is hurt, you step forward without hesitation.

According to Kaji, the middle school years were the most handful

It was apparently the "worst brat era" 😇
