As we can see above, this haircut:
- Is dark in the back, blached in the front
- split into minimum two groupings: Body and Bangs
- Spiked in the back, likely with the use of gel or styling mousse
Obviously this is an anime, and as other features such as eyes, ears, and legs are exaggerated I feel it is safe to interpret the length of hair as exagerrated as well.
This is a convenient assumption because otherwise, spiking shoulder-lrngth hair into seven (minimum) rigid vertical spikes would be impossible to maintain.
Assuming a real-life Yugio haircut could exist as inspiration got this style, I imagine a haircut that is either short and spiked in the back with natural bangs, or long in the back and textured with shorter bangs to frame the face. Either way, either the front is bleached, or the additional blond spikes in the back could be interpreted as highlights throughout the darker, perhaps natural hair.
Given these criteria, I have narrowed the possibilities dow to these three hair styles:
