Ayanokouji Kiyotaka's Black Basket Journey.
Brother Lu's disastrous journey as a squad leader~
PS: I haven't read the original version of A Classroom, only the anime. What Brother Lu said in the last episode inexplicably matches that of the team leader!
The first person is called the Lord, and the character is seriously OOC. Try to restore the image "in my mind" as much as possible!
Don't mind Xiaobaiwen, just enjoy reading it O(∩_∩)O
