Sonic looked over the board one last time before giving a casual shrug and turning on his heel, continuing on his way with arms folded leisurly behind his head. Nothing exciting today it seemed, but he knew there were other interesting things to do elsewhere.

(If you wanna interact, feel free to :3)

She decided to introduce herself
Sort of at least.
She picked up a small rock and put a paw print on it.
" show my hero name."
Then the black changed to the word Rune
She then took aim
( She is going to have it land on his head if you can't guess. She also switched to her hero form.)

Sonic halted abruptly and raised his quills on instinct as something hard hit him from behind, bouncing off the back of his (decidedly thick-skulled) head. He let out a soft grunt and spun around, looking down at the projectile. Where'd that come from? He wondered, picking up the smooth stone and turning it over in his hand.

He blinked in slight surprise upon noticing the inscription, then glanced around. He heard somewhere that people used to carve messages (albeit they were usually taunts directed at some unlucky victim to add insult to injury) into slingstones back in the days of old, and he wondered of it was meant for him or he was reading too much into it. After a brief survey, nobody on the street seemed to be paying him much mind at the moment, but a figure on one of the rooftops above him caught his attention. The sun was behind the figure though, so all he could make out as a dark shilloette that looked vaguely cat-like.

" flatten."
The stone flatter out into a disk.
She then changed the message to
" I am Rune. It is nice to meet you."
She watched him.
She wondered if he would freak out at the changing stone

The shift in the palm of his hand did catch Sonic's attention, but not in the way Rune was probably expecting. Instead of panicing, Sonic's face broke into a wide grin. Looks like today won't be boring after all! He thought gleefully.

He skimmed over the new message and took a step back, trying to get a better look at the figure above him. Deciding it would be rude not to answer, Sonic lifted a hand in greeting. He gestured to the stone, then up at the feline questioningly, as if to ask 'Are you doing that?'

She took this to mean that he was used to weird things like this
She changed the message to
" Maybe. I can do other things."

Sonic's ears tilted foreward in interest, as he backed up another pace, curiosity having officially gotten the better of him. He paused and scratched the back of his head breifly as an idea hit him. He held up both hands in a 'Wait there' gesture before trotting back a couple more yards.

Turning to face the building, he took a deep breath, then charged headlong towards the wall. Mere miliseconds before a would-be collision, he adjusted his footing in a practiced motion and redirected that momentum upward, sending him streaking up the side instead. Once he was near the top, the hedgehog steeled himself and pushed off, springing upward and landing on the rooftop with a flashy somersault. He easily hopped back to his feet and straightened, smoothing his quills down with a grin. "Hey."

She jumped at that
" come"
The stone immediately came to her and she caught it in her hand
She then let out a sigh
" 3 with super speed. 2 who can be somewhat predictable. 1 to learn about. I take it that you must be Sonic."
She quickly used her paint to make a circle around herself
" let nothing into this circle."

Sonic flashed a confident smirk. "You guessed it." He chimed. He looked the cat up and down curiously before flashing a sheepish grin. "Heh, you look a bit shaken up. Sorry about that missus... Rune, y'said your name was?" He went on, tilting an ear.

" no. The rocks name is Rune."
You could hear the sarcasm in her voice
