As it is known, President Soekarno has a grandson named Frederik Kiran. Yes, he is the child of Kartika Sari Dewi Soekarno. Kartika Sari herself is the offspring of the Proclamation Leader with Ratna Sari Dewi Soekarno, a woman from Japan.
Indeed, now Ratna Sari Dewi Soekarno, or often called Dewi Soekarno, prefers to settle in Japan. Her life is happier, especially with the presence of her grandchild, Kiran. This is their togetherness.
