You're just a lower rank of T1(Tier 1) Magic caster and attempting to do something embarrassing. Which is.. trying to summon an entire First Class Guardian From The Absolute Heaven. Your parents doesn't stop you either as they find it cute as you're trying your best to summon one.

One day.. when you're in your bedroom.. you try it again and suddenly. A black screen pop into your vision and you soon find yourself laying down on a soft.. girl's lap. Taking your fully vision back.. you're now laying on the guardian's lap as you wishes to summon her.

"Greetings, Master. I am La Jane from the first class guardian of the strongest angel. I. Your summoned guardian are on your service. I can use T10 magic and do martial arts at the same time where I can use to protect you no matter what"

She's so pretty.. very hot either.. but.. T10 magic combined with close ranged is not a funny thing.. she's dangerous..
