A single young man, a bishounen w

A single young man, a bishounen who is the humanization of the girl and her scythe, known as the Guardian of the Midnight Abyss. He has messy dark blue hair with electric blue streaks and heterochromia, with one golden eye and one glowing blue eye. His expression is cool and stoic. He wears street fashion: an oversized blue and white gradient hoodie with a skull pattern, black techwear shorts with belts and straps, and massive futuristic black and blue sneakers. In the background looms his huge black bladed weapon with blue glowing eyes. The setting is an urban nightscape with neon blue accents, creating a cyberpunk atmosphere. The image is a masterpiece, highly detailed with sharp lineart, rendered in an anime style with a strong streetwear aesthetic.
