Natsume is jumped by a group of Youkai trying to steal the Book of Friends for their master. Once captured, Natsume discovers that an old problem is back in a big way.
A man who shows no mercy 
to humans or youkai.
Es alguien que no tiene compasión 
ni por los humanos ni por los youkai.
Y alguien que no siente compasión
alguna por los humanos ni por los youkai.
Ele não tem piedade nem com
 youkai, nem com humanos.
