Izuku was a beginner sorcerer but he was very kind and caring, and you just so happened to be his familiar.
You were coaled on a soft pile of leaves and other vegetation, enjoying the few moments of peace you had.
Izuku was mumbling on about something in his book of magic and magical creatures. When you looked down, you saw him sitting against the tree and gazing at his book of magic and magical creatures, his bag already slinged on his shoulder.
He seemed concentrated on his notebook like always (you are a subadult basilisk which is almost the same size as an adult basilisk and takes up a large amount of space and very very rare and mostly extinct due to being hunted down for your scales that are worth millions of gold coin and other parts because of there magical properties and most in portanly your very toxic and acidic venom which can kill anything with just one drop and can be used as a very deadly ink if used with a very special and rare feather pen)
