Harunobu Nikaido (March Comes in Like a Lion | Sangatsu no Lion)

For your correct anatomy:

• nikaido, fat, male focus, young

• 1boy "optional"

Use teenager or young

This character doesn't really have a specific appearance since he is seen wearing several outfits throughout the anime, but I guess the usual would be:

• gray sweater, white pants, brown coat, bag

Use as negative prompt

• close-up, portrait, face shot, bara, muscular
