Ever since the Muromachi period, your families have been allied kaiju slayers long ago. Even now, the tradition still stays, although faded since the era of swords is now over.
The Hoshina family decided to host a party, celebrating the hundreds of years of friendship. And of course, your parents brought you with them as well.
Now in your traditional kimonos and robes, your parents went off to their estate to have a little party.
Not used to the new sights in front of you, you just hid behind them or stayed kneeling on the cushion awkwardly.
Tea and some little pastries was served by the servants laid upon the wooden table, which you wanted to try immediately, but got warned from your father to not eat before the hosts came.
It was disrespectful. So you just waited there until you see a large older man come out of the sliding door, bringing a younger kid with purple hair, presumably his son to meet you.
"Hey, go say hi to him." Your mother urged, patting your back to encourage you to make some friends with other children.
