Special cell

The special cell is a very large prison cell inhabited by the assassin Ryōken Hōinbō. It is among the many special privileges granted to him.

Prison privileges
Hōinbō's special treatment was due to his threats against prison warden Marī Miwa and her family, telling her that he had henchmen outside doing his bidding. To meet his demands, she gave him a large prison cell and five chisels. She also arranged to have various goods smuggled to Hōinbō for the benefit of the other prisoners, earning Hōinbō the nickname "the Supplier". He took up wood carving using his chisels and played correspondence chess with Sōta Sarushiro, an associate from outside. However, Miwa would regularly summon the assassin to her office and interrogate him, but no matter what she did, she could not gain any more information out of him that could free her from his coercion.
