Summary
After lunch, you both walked to the very edge of the park, past the boutiques and bustling playgrounds, and onto a dirt path winding through a small patch of greenery.
It must have been an odd sight to see— A human blabbing their mouth at a (pretty scary-looking) monster who may or may not be speedwalking to get them off his tail.

Summary
In a linear, closed off yellow-hued hallway, featuring a Symbolic Rune depicted atop the corridor entrances and windows. White light shines through the mosaic windows, and Greek pillars border the corridor in both sides Mami, Sayaka, and Madoka are cautiously walking in the middle of the hallway to reach the end, until they stop as a girl with long black hair like Homura with slightly pale skin and has black eyes with white pupils made herself known appearing from a pillar and was wearing her seemingly signature blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of white slippers and was showing her signature smile to them.
"..."
??? Looked at them curiously and then spoke. "That expression that you're all wearing..."
"..."
"Well, i won't grace it with a description. But damn this is your 900th try so good luck. Kyoko and Nagisa are waiting for you three, you know?"
"S-Sachi-san please we can try and talk this out-". Before Madoka can finish what she's saying, Sachi Akemi looked her with her white pupils missing.
"Talk this out?" Sachi scoffed "You lost that chance after what you did to Homura" -

Mind him, it isn't his fault Murder decided to be a bitch this early in the day.
Killer—
Doesn't answer.Water ripples against his knees as Killer moves, not just testing the water or rubbing away at Sans’s legs but— he…joined in.
The silence is even louder than the screaming of the dead.

Summary
The leader of the human province and head mage, Cadoc, has no qualms in letting anyone willing to listen know that his third daughter—an unassuming girl with a deep blue Soul—has the most powerful magic known to mankind. She's able to perform feats that would make the entire monster kingdom tremble in fear. She may even have enough magical prowess to tip the scales of power between the already tentatively peaceful neighbors.
Reluctant to violence, but hand forced with the protection of his recently unearthed populous, King Asgore levels the humans with an offer. Hand over this Blue mage to be paired with his Son, in a show of unity between their nations. Eager to breach the tall walls of their secret kingdom for information, Cadoc agrees.
Unbeknownst to all, there's a third party at play, who's been intently watching the Head Mage's daughter as she spends her time in the meadow between their lands. She's nothing like everyone says she is... and soon he finds he's fallen for her—hard.
When the Prince agrees to switch places with him for the courtship ritual, her secret admirer will have to win her heart, and Soul, sight unseen. But can they both keep pretending to be someone they're not?

Summary
Trading her freedom away for the safety of another, this book loving woman finds herself in a strange castle, guarded by the castle’s inhabitants. Unbeknownst to her, these four have another fate in mind for her… they’d agreed to her deal in hopes that she could break their master’s "curse".
With a heart as firmly guarded as their realm, the dark beast that reigns over the castle is resigned to a future alone and unloved. With a job as nasty as his self image, there’s no way this kind stranger could ever care to look upon him… right? Can a caring hand light a fire in this realm of permanent midnight?
A tale as old as time, told in a new way.
