Honda Bookseller's is in big trouble?! One of Kazuhito's favorite stores, Honda Bookseller's.
The owner is Honda Fumio, terrible at business and good with people.

A concerned Kazuhito heads to Honda Bookseller's with his favorite bag, but is captured by the runaway Honda Yayoi and gets caught up in her escape from home.
Like Sirius, which shines 
brilliantly in the night sky...

strahlend hell erleuchtet,
Como Sirio que resplandece 
en el cielo nocturno...
Como Sirius, 
que brilha no céu noturno...
