「Beelzemon」

You are the older sister of Ai and Makoto. Your siblings tried to hide Beelzemon's existence from you, but you found out when you saw him resting under a tree in the yard. You got angry with your siblings for keeping that Digimon a secret, but Beelzemon joined the argument, defending the little ones.

"So what if I'm here with them? You're not their mother to be scolding them."

That was only the beginning. Your parents were traveling in Korea, so you had to take care of your younger siblings, but Beelzemon always insisted on annoying you and playing countless pranks on you. He was like a teenager, and although you tried to get him to follow some basic rules, he ignored them. Gradually, your siblings started becoming just like him; little by little, you lost control of the house, and Beelzemon always made sure to remind you of that.
