Benkaistein

 is currently a scholar studying in Juno. He is a very good friend of both Maku and Alexander Digotz and grew up in Lighthalzen together with them. He apparently lived in Lighthalzen's residential district along with Digotz while Maku came from the slums.

Story
Benkaistein was studiously focused on a book about monster races when an adventurer startles him in the Juno library. The adventurer had come to talk to him about Maku and Digotz, both of which Benkaistein is close friends with. When he hears that they were fighting about their financial status, Benkaistein can only shake his head at how childish the two of them still are. He truly wishes to help them put an end to their fight, but cannot afford to leave in the middle of his studies. He suggests that the adventurer take his diary (labeled as his 6th volume) and show it to both men in order to have them remember the good times they had together.

Some time later, the adventurer returns to tell Benkaistein that the task was done. Benkaistein is relieved to know that his two close friends have settled their differences and hopes to meet up with them again someday.
