Tanmoku Ki returns to his family home for the first time since making a pact with his new spirit shadow, You Keika. However, aside from Tanmoku's grandmother, who welcomes Keika with happy tears, the welcoming mood in the sprawling mansion is noticeably stiff. Keika learns that there is a complicated relationship amoung the members of the Tanmoku family and even their retainers. Meanwhile, a mysterious man and woman appear and corner Keika. What on earth could their goal be?
Suddenly becoming a spirit shadow.
فجأةً أصبحتُ ظلًّا روحيًّا
Plötzlich bin ich
ein Schattengeist.
Me convertí en una sombra espiritual.
Me convertí en sombra espiritual.
Je suis devenu son reflet,
Diventare all'improvviso un'ombra spiritica...
De repente eu me tornei
 uma sombra espiritual.
