I was the one who liked her first… My childhood friend, who shares the same strategic goal as my beloved grandfather—to become a professional Go player—is now addicted to a middle-aged man's penis and becomes his sex toy. Matsumoto Ichika MKON-088

This child is Matsumoto Ichika. She's my childhood friend. Ichika's grandfather, Matsumoto Masatoshi, was a legendary shogi player. As her grandfather's successor, Ichika inherited his signature move, "Boku-giri," a powerful technique I've never beaten... I love her as a friend, a rival, and a woman. I've decided to tell her my feelings one day when I defeat her.
