S01E05 The Peach Blossom Spring Dance

Just as Ichiyo is joyfully reunited with Hakugo, a massive earthquake rocks the Immortal Realm. Amid the turmoil, it's discovered that all the Peaches of Immortality, which Kashi was meant to take to the outside world courtesy of The Queen Mother of the West, have vanished. Ichiyo's mentor, Ran Saiwa, is detained for questioning, prompting Ichiyo to team up with Ryusei to journey to Japan in search of the culprit behind the theft.
