One morning, at the end of one of their usual arguments, You Keika learns about the life and death relationship between a Youmeishi and their spirit shadow, as well as the weaknesses of this from Tanmoku Ki. Along the way, Keika learns about the Tanmoku family's treasured sword (the Rakugetsu sword) as it is being taken to the family mausoleum in preparation for the pledging ceremony. He then finds himself under attack by Shito Ritsu who bears a strong grudge against Tanmoku Ki. When he soul is about to be broken apart Keika reaches out for the sacred sword...
If it wasn't for the Youmeishi, you'd 
just be some useless wandering spirit.
لولا اليوميشي، لكنتَ مجرد روحٍ هائمة عديمة النفع
Ohne deinen Yōmeishi bist du
nur ein nutzloser Wandergeist!
De no ser por el youmeishi,
serías un alma en pena.
De no ser por el youmeishi,
serías un alma en pena.
Se non fosse per lo Youmeishi,
saresti solo un inutile spirito smarrito.
Se não fosse pelo Yomeishi, você
 seria mais um espírito vagando.
