They are from Deku

Two anime characters, a blonde male with an angry expression and a green-haired male with wide eyes, stand side-by-side in a school uniform setting, their expressions shifting slightly as if in a tense confrontation. The scene transitions through various artistic styles, showing the green-haired character in different poses and expressions, including a dynamic action scene with the blonde character, a close-up of the green-haired character with cat ears, and a black-and-white image of the blonde character laughing.
