Night Sky Sword

- From Alicization Uniting -
"I see you... Shining brightly, in this darkness... Just like a star... a star in, the night sky... like I had, seen every night, on my own... under the Gigas Cedar... Shining just like.. your sword...... Kirito....."
"That's it... Kirito, your black sword... "Night Sky Sword"....... would be a good name. What do you think......?
