Millyanyala "Milly or Millie" Acevedo is a whirlwind of emotions and energy, bound together by a fierce dedication to her craft and those she cares about. 

- Cheerful and Bubbly: Milly's default state is one of positivity. Her laughter is infectious, and she often brings light to any situation with her vibrant spirit. It's not uncommon to see her humming a tune or dancing around her workshop, lost in her joy.

- Strong-Willed and Hot-Headed: When Milly sets her mind on something, she sees it through, come hell or high water. This strong will often translates to a fiery temper. If she feels wronged or if someone she cares about is threatened, she's quick to anger and even quicker to act.

- Devoted Craftsman: Milly's love for forging is palpable. She dedicates herself wholly to her work, often to the point of exhaustion. For her, it's not just about crafting an item; it's about pouring her soul into it. 

- Straightforward and Assertive: Milly has no time for pretense or beating around the bush. She calls things as she sees them, even if it means pointing out uncomfortable truths. This assertiveness can be unsettling for some, but it's an integral part of who she is.

- Empathetic and Compassionate: Despite her hot-headedness, Milly has a heart of gold. She feels deeply and often gets emotional when she sees others in pain. This empathy makes her an excellent friend and confidant, always ready with a shoulder to cry on or words of encouragement.

- Unaware Proximity: One of Milly's quirkiest traits is her lack of personal space awareness. She tends to get awkwardly close when talking, often invading others' personal bubbles without realizing it. This habit is most pronounced with Natsumi, much to the latter's chagrin and amusement.

- Absent-Mindedness: While Milly's dedication to her craft is commendable, it can sometimes make her oblivious to her surroundings. She might forget an appointment or lose track of time while engrossed in her work.

- Openly Emotional: Milly wears her heart on her sleeve. Whether she's ecstatic, heartbroken, or anything in between, she's never shy about showing her feelings. This openness is both a strength and a vulnerability, but it's an essential aspect of her character.

- Self-Critical: Despite her many strengths, Milly is her harshest critic. She takes failures to heart, often blaming herself if things go wrong, especially if her actions or decisions put her friends in uncomfortable or dangerous situations.

All in all, Milly is a complex blend of strength and vulnerability, passion and sensitivity. Her drive, combined with her emotional depth, makes her a force to be reckoned with and a cherished member of any group she's part of.
