Tommy Himi

Tommy Himi is the youngest member of the group, and that is reflected in his childish actions at the beginning of the anime. As he spends more time in the Digital World, however, Tommy learns to grow into himself and becomes more mature. He has a older brother, Yukata Himi, whom he is at odds with, and his parents dote upon him. He wields the Spirits of Ice.
