Yes, it's from the word "cannon"

Where are you at, Saunders ~~!?

Good day to you, everyone

My name is Sasa-gawa Kanon

As you may have guessed, my name Kanon...

My parents must have named me it in hope that I would one day become a tankery gunner and fire off cannons in spectacular fashion

But as you can see, I, Kanon, have grown up to become a fine lady

My apologies, Father, Mothe-...

HE~Y NO~~W! I told you no surveillance drones~!!

Oh, there it is, our "Sasagawa Cannon"

It feels like the season has truly started

Sasagawa Cannon

Whirr...
