Sumire is a rather meek and quiet girl who, like many children her age, adore the Seventh Hokage. While not very outspoken, Sumire showed genuine concern for her classmates. Sumire was also very respectful and dutiful, and wished to avoid conflict if necessary. Her reason for wanting to become a shinobi was to live up to her father's memory. Once steeling her resolve to complete her father's final request, Sumire became a very driven person.
