"Onitama?" Cain, who was reincarnated as a character targeted for the otome game, screamed at the loveliness of her sister, Diana. It's unbelievable that this angel will be the villain's daughter who will end up in many ruin — no, there can't be such a future! If you hold your fist firmly, you will raise your sister into a gentle lady, and in the place of the heroine, you will wipe out the darkness of other characters targeted for capture one after another. Reliance is the game knowledge of the previous life and the orphan's chamberlain. Everything is for my beloved sister—my brother's challenge is about to begin! "I ate onitama, di, and carrots!" "Great! What a wonderful Diana !!!" A full love fantasy of avoiding ruin, where my brother loves my sister today!
