His Family
Yes, we all know Izzy was adopted. His mom and dad were killed in a car accident, so he went to live with his aunt and uncle. He has no other family...so here they are! Izzys mom (aunt) and dad (uncle)!
Mrs. Izumi - Izzys Mom (Aunt)

Mrs. Izumi is very nice. She's always worried about Izzy, and making sure he's ok. Tentomon thinks she's very pretty, and a good cook :) Now we know what side of the family Izzy gets his good looks from! She likes to make food for the team (especially in 02) and is always eager to help them out in any way she can.


Mr. Izumi - Izzys Dad (Uncle)

Mr. Izumi seems like the father/son type guy. He trusts Izzy allot, and always seems to be concerned with his school work. You don't see him much, but he's the guy who keeps Mrs. Izumi's head on straight, and keeps her from becoming a frantic and worried mother about lil' old Izzy. He usually thinks before jumping into situations.
Hello? Izzy! It's about time you called! You're where? Outside the school, being attacked by millions of fan girls? Oh I'm so happy for you! My little boy is growing up!...Help you?....why?
