What do the twins do in their daily life?
Kawakami Kakuka will tell you that she tries to 'kill' her brother every day and has come up with countless failed plans for this.
Bat: I have adopted two more children, let me introduce them to you.
Bat: (Looking at his sister) This is my brother, Kawakami Kakuhua, you can also call him Victor.
Bat: (looking at his brother again) This is my sister, Kawakami Shishu, whose English name is Catherine.
Bat: (nods) That's right.
PS.
1. The two protagonists, the elder sister and the younger brother, seriously want to kill each other in the early stage.
2. Women dress up as men and men dress up as women. Goldfinger is a dress-up system. Clothes have attributes and skills (not too outrageous).
Mission: Cubs are the treasures of the world.
