I’m going to walk you through how to draw Kengo Haryu from Blue Box. This version focuses on his full-body look in school uniform. The drawing is mostly straightforward, though you’ll want to pay attention to proportion and the structure of his posture. The character design uses clean lines and balanced details, which makes it manageable even if you’re not used to full-body sketches.
Key Elements of Kengo Haryu’s Design
- Short hair, slightly spiked and combed on the side
- Loose-fitting school blazer with a V-neck sweater underneath
- Collared shirt with necktie tucked into the sweater
- Long pants with a clean crease and simple shoes
- Relaxed, slightly formal posture with one hand behind the neck
Next up, you might want to try drawing characters like Taiki Inomata, Chinatsu Kano, or Hina Chono from Blue Box – I’ll add them as soon as they are ready.
