Several options, playing with different aspects of "Blaze" and fire quirks:

Playing on "Blaze":

• Blazefire: Simple, direct, and emphasizes the fire aspect.
• Blazefury: Adds intensity and a sense of anger or aggression.
• Emberblaze: Suggests a smaller, more controlled flame, perhaps hinting at a more strategic or precise use of the quirk.
• Blazeheart: Connects the fire quirk to the character's core being.
• Blazeclaw: Implies a physical fighting style incorporating fire.

Incorporating Fire Imagery:

• Cinder: A subtle and evocative name suggesting burning embers.
• Ignis: Latin for "fire," lending a sophisticated feel.
• Phoenix: A powerful mythological bird associated with fire and rebirth.
• Inferno: A strong and dramatic name suggesting intense heat and destruction.
• Magma: Suggests a molten, powerful fire.

Combining Approaches:

• Cinderblaze: Combines the subtle "Cinder" with the direct "Blaze."
• Ignisheart: Combines the Latin "Ignis" with the emotional "Heart."
• Phoenixfire: A powerful combination of mythological imagery and direct reference to fire.
• Magmafury: Combines the powerful "Magma" with the aggressive "Fury."

Adding a Surname:

Consider adding a surname to create a more complete identity. Surnames could be based on:

• Location: Yamamoto (mountain), Akagi (red mountain), Hi no Tori (fire bird).
• Family history: A surname reflecting a family legacy or tradition.
• Personality: A surname reflecting a key personality trait (e.g., Kageyama - shadow mountain, suggesting stealth).

Ultimately, the best name will depend on the specific character and story. Consider the character's personality, fighting style, and overall role in the narrative when making your final decision.
