The third drawing of the sequence is from Misawa Daichi or also known in the West as Bastion Misawa from the anime, manga and video game series Yu-Gi-Oh! GX.
He is a student at the Ra Yellow dormitory with a lot of potential to become a great duelist.
I made this drawing based on its drawing that I did on the paper previously and then I colored it.

More info about Misawa Daichi below:
"Bastion Misawa, known in Japan as Daichi Misawa, is a highly analytic Duelist who resides in the Ra Yellow dorm at Duel Academy. Bastion is a mathematical genius who covers his cards and the walls of his room with endless numeric formulas, believing that everything in life can be calculated arithmetically. The neglect of his character is a running gag throughout the series in the anime as well as in the manga version of GX..." - Source: Yu-Gi-Oh! Fandom.
