Hoonts' Mysterious Quest

Grab a pen and paper, be ready to write.
For I've hidden a puzzle in this year's artfight.
I'm simply the quest giver. I have no clue,
but my friends below, each of them do.
Go. Search. Bring them together.
They build a grand word, letter by letter.

Each person below has hidden a red, bold letter among their character profiles.

Look in a mirror
Think very hard
Now use the letters found
to claim your reward

Once you've figured out the secret word it can be added to the end of this site's url with a hashtag to claim the prize.

You've earned your prize!

Serendipitous
Serendipity

The luck of finding something useful
while searching for something else entirely

Thank you for playing!
I hope you found some interesting characters to attack during your searching!
Please don't share the answer with others, let them have a chance to figure it out on their own.
For your reward have a badge and a mini tutorial!

Feel free to add this badge to your profile to gloat about finishing my little quest~

Ha ha! Very clever!

Cute, but you need to find the real password to earn your reward.
