Bossun has a new e-mail friend, as does Himeko... In fact, they both start to fall for their respective pseudonymous pal, unaware of the person's true identity!
Indeed! This is Sanada-maru, 
built by Sanada Nobushige!
¡Es la fortaleza que construyó 
Nobushige Sanada, llamada Sanadamaru!
¡Por supuesto! ¡Es Sanada-maru, 
construida por Nobushige Sanada!
Realmente! É a Sanadamaru que
 o Nobushige Sanada construiu!
