Shinji Toyosaki  

, 豊崎シンジ

The current head of the Toyosaki household took over after the previous leader passed away. Although the former head had left a safe, he did not provide the password for it. If someone tried to open it without the correct password, the entire safe would ignite in flames. To prevent this from happening and also protect the safe from thieves who wanted to steal it, the new head hired Hamatora to attempt opening the safe and safeguarding it.
