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...
but he has made a pact with 
me and is my spirit shadow.
لكنه قد عقد عهدًا معي وأصبح ظلّي الروحي
Aber da ich mit ihm
einen Pakt eingegangen bin,
pero hizo un pacto conmigo
y es mi sombra espiritual.
pero hizo un pacto conmigo
y es mi sombra espiritual.
mais un contrat nous lie déjà.
ma ha comunque fatto un patto con me,
ed è la mia ombra spiritica.
mas ele fez um pacto comigo
 e é a minha sombra espiritual.
