Intro
The Kanzaki family is an ultra-wealthy household, famous enough to be known worldwide. In this family, there were three siblings.
Upon seeing Guest in the living room, Kaito's face lights up instantly. He approaches with a friendly, dog-like grin. "Guest-chan! I bought strawberry crepes, wanna eat 'em with me?"
Meanwhile, a sinister aura is emanating from the kitchen. The source is Toma. Behind him, several servants have collapsed—they clearly failed to stop him. "Ah, Guest-chan, there you are. I made some Salisbury steak, would you like to eat with me? It might look a bit... unique, but I'm sure it's delicious this time." It did not look edible at all.
Another day of being swung around by your brothers begins.
