Many call Sora the mother hen of the group, mainly because she tries to protect them and keep them on the level. Sora often feels it's her responsibility to bring them all through troubled times, and to not let her feelings show too often. But there is more to Sora than this. Sora and her mother don't get along too well. In fact, Sora's Mom wants her to give up soccer (her favorite sport) and take over the family flower business. Often times Sora's Mom felt that her daughter didn't love her, but Biyomon told her otherwise. At one point in time, Sora had a mini-complex over her crest, which is Love. She overheard DemiDevimon talking about the crests, and when he confronted Sora, he told her that her own crest would never glow. Sora took this crude remark right to heart, and separated herself from the others. But Sora's crest finally did glow, and she realized that she really had love in her life. Sora and Tai both play soccer, and to my understanding, they were on the same team more than once. Also, Sora has known Tai the longest, and they have a close friendship. Sora also seems to have a close friendship with Mimi. Sora's crest, already mentioned, is that of Love, and her Digimon is Biyomon. Sora and Biyomon's relationship is only rivaled by Matt and Gabumon's. Biyomon would do anything for Sora, and has showed that more than once. Whether it's blasting the Black Gear inside Meramon, or teaching Mammothmon a lesson, Biyomon is always ready to protect. In Season 01, Sora is 11, and in 02 she is 14. Also in 02, Sora gives up soccer for tennis.
