I spent two years in the death game "Ian Grant in Floating City" (the appearance of the characters in the game changed slightly over time). In the game, he owns a swordsman in black (Ao の), a liar, a barrel boy (known as "Brother Mouse") and the boss of the barrel boy (known as Klein). From the first season animation (sentence 21) about 9 minutes 15 seconds, it can be seen from his conversation with Naoya that the academic performance of Tong Ren is quite excellent in reality.
The motto is: find what is lucky and available in misfortune and make good use of it. (Excerpted from Chapter 6 of Volume 5 of the novel)
