BJ is a member of 777's band, Def Märch, along with Tenho. He has a crush on Uzuki Yashiro, but nothing comes of it. BJ first appears in Week 2 Day 3 when 777 loses his winged microphone. 777 suspects him because BJ frequently whines about wanting to perform the vocals in their band. Joshua and Neku prove his innocence by making him confess to calling Uzuki in the "Phone Booth of Love". BJ and 777 later reconcile over the mic and vocals after the mystery is solved. He later appears with 777 and Tenho, who tell them that they are using Minamimoto's megaphone to sing.
He also appears in Another Day with 777 and Tenho to play Tin Pin Slammer with Neku and his friends.
- BJ is a normal, black hooded Reaper, dressed in a similar style to many other Reapers. Though he is never seen performing Reaper duties, he is presumably a Harrier Reaper.
