First appearing in The Volume of Revival – Part 6 (North West), Yukari is Yuna's mother who works as a broker in Italy. The first impression Yukari gave out to Kazuki was that she is a beautiful traditional Japanese woman, but actually she was the one who had taught Yuna that it is bad to lose, which had led to Yuna's easily jealous character. Yukari had once chased Kentaro all over the world before finally cornering him at the summit of Kilimanjaro and forced him into agreement to marry her.
