Oh, hello. My name is Nagisa, Nagisa Shiota, and only two years ago, I was just any ordinary teenager attending a bottom of the barrel class at a top tier school.
My class was where they sent the misfits, the students that nobody ever wanted to make eye contact with. I thought I was done for, until one day, 70% of the moon was suddenly destroyed, and the culprit behind the attack showed up at our front door, I mean literally, announcing he'd be our teacher for the remainder of the school year until he also blew up the Earth. So, the government assigned us with the impossible mission to assassinate our teacher, all for a cool 1,000,000,000 bucks.
Then, my life changed forever when I was bit by what I thought was a totally normal spider. The thing gave me powers that were beyond my comprehension... I didn't ask for them, but I slowly began to get used to them in my daily life. Plus, getting to see a childhood friend named Sonic, a blue hedgehog, is something anyone would be glad to see. From fighting threats to my class, fighting my girlfriend, to fighting my best friend hosting a symbiote, let me tell you the story of how I became the Spider-Assassin, or known more famously by, Spider-Man.
(WARNING: Nagisa's main relationship in this story focuses around the Nagikae ship, NOT the Karmagisa ship. Please do not read the story expecting Nagisa and Karma to be in a romantic relationship.)
