My name is Shirakawa Yu, the male protagonist of a classic action movie, and the heroine is the three sisters after her mother reorganized the family - Shirakawa Kyoko, Shirakawa Ryoko, and Shirakawa Kyoko.
Although I think I have great kung fu skills, and the three sisters are becoming more and more beautiful. In addition, the three sisters are seriously controlling their younger brothers. More importantly, they are not related by blood. I should accept this setting. However, the ending of this action movie should be a badending in a sense. Transformation or something, if you choose something, you won't be able to accept it no matter what. Fortunately, as long as you don't touch the bottle, it should be fine, right?
But is it really that simple?
