(Male Second Person to Mouse)
“By the power of my Command Seal, Caster! I order you to protect my by any means you see necessary!” You call it out with an authoritative tone, reciting the spell just as the lavender-haired beauty had instructed.
A smile spreads across her features, and for a moment you could swear that you see her pointed ears do a slight, contented twitch. “As you wish.” She says, an easy confidence to her nature. Now that you’ve given her the command and the mana to use it, she’s fully in her element.
For a moment, you watch her do strange, hypnotic, swaying motions with her arms. Then the effects of her protection spell start to settle across your body.
There’s an electric tingling along your every pore, and you can feel your hairs standing on end inside your clothes. You grin to her, unable to keep the excitement from your voice. “Caster! It’s working!”
She echoes your smile with one of her own, though hers somehow manages to combine playfulness with malevolence. At once, you realize that something has gone distinctly awry, even before she starts to speak. “Of course it is, my little pet.”
You feel it in your teeth first, namely your front ones. They ache like someone’s pulling on them with pliers, and you find your head instinctively leaning forwards, as if you can ease the pressure that way. It doesn’t help much, your neck can only angle so far. But the pulling continues, and only intensified.
“Whathgoinonnnn!” You protest with a grimace. Your face starts to stretch like putty before your eyes, and you watch your nose twitch. It looks familiar for some reason, even though gray hairs have begun to cover it.
“Oh, sweet Master. I did just as promised. I’m keeping you safe.” She smirks like the cat that just ate the canary, and you wonder how deep the rabbit hole you’ve gone. Your next change provides you an answer, and tells you that while you’ll be spending a lot of time in holes, they won’t belong to rabbits.
The ache in your teeth is mirrored in your spine, and a pink, hairless tail extends from your backside. There’s a faint tuft of fur where it meets your backside, but otherwise it’s mottled in fleshy pink and gray alike. It’s undeniably a mouse’s tail, and you squeak in distress.
“Squeaking already? My, my… So good to see that you’re getting into character.”
You look back to Caster to find that she’s a head taller than you. She uses this newfound height to her advantage, petting your head and sending a tingling along your scalp. Hairs flutter into your field of view, and you realize that you’re shedding your old human hair.
“N-no! I’m your master! You can’t do this to meek!”
You squeak faintly, and have to suppress a whimper of helpless denial. Your nose feebly twitches, betraying your distress, and you curl your swelling upper lip as best you can with disgust. Becoming an animal is an ignoble fate enough on its own. Toss in being a mouse, and everything gets so, so much worse.
Whiskers curl from your upper lip, drooping low off your face. They sway sensitively with every movement of your body, and you pet them in stunned disbelief. They have to be at least half as long as you are tall, even in your shrunken state!
Much to your relief, you find them shrinking along with your body. Much to your shame, you realize that you were relieved. You find yourself having to look up a bit more to meet Caster’s eyes, having dropped another foot in a matter of seconds.
“Years to grow so tall, barely a minute to take it away. Humans are such woefully susceptible creatures, wouldn’t you say?”
“Pleek! Neek uhheek HEEK EEK EEK!” Your attempt at a plea degenerates into feeble squeaks, and you shrink smaller and smaller and smaller still. It’s like your body is trapped in an ever-shrinking mold, warping you to its new form.
You can feel your belly swelling up just as your torso shrinks. Your arms and legs shorten, while your fingers grow much slimmer. Your toes splay, lengthening into the hindpaws of a rodent. It’s all happening so quickly, and yet you feel as though it’s been years since you’ve started to change.
“EEK!” You wail again, the sound even louder. You don’t need anyone to tell you why, you can feel it yourself: your ears are growing larger, rounder, softer. At the same time, they’ve become much more sensitive.
You’re small enough now to fall within your clothing, and you find that you’re trapped in a seemingly endless ocean of fabric. Then, you see a light. You scramble towards it, nose twitching like mad. Fear, true fear settles into your heart. You’ve no doubt it’s because a part of your brain has become mousy, but you still bolt the instant you’re able to.
“Wha-hey! Master! Get back here!” Caster sounds worried. Well, too bad for Caster, she’s not the one turning into a mouse. Scampering free of your clothing, you evade her grasp and manage to slip through the small hole in your doorway. Ironically, it’s one made by a mouse you’d later trapped.
Well, rest that rat’s poor soul, but also bless it for saving you. You’re free, though the world looks so much bigger… And worse, too. You’re nearsighted to the point of near-blindness, everything looking so blurry around you once it’s more than a foot from your constantly twitching nose.
You realize, with a start, that you’re moving naturally on four legs. Of course, this leads to you tripping over them, skidding out from another mousehole into public view.
The loudest piercing shriek assails your round ears, and for a moment you’re worried you’ve stumbled into some kind of banshee servant. Then you look up and find a pair of mouse-print panties normally concealed by a skirt.
You don’t have time to appreciate this view before an oversized foot comes crashing down beside you.
“Mouse! Kill it kill it killit killitkillitkillit!!!”
It’s a group of girls from the nearby high school, and all of them seem to want to play Whack-A-Mole: Grimdark Edition. It looks like they won’t be sated until you’re a smear below their shoes, and you do your best to run around their feet.
Surprisingly, it’s easiest to move when you don’t think about it. It’s probably got something to do with how you don’t remember how to breath, or how as a human you never noticed how your tongue never sat perfectly flat in your mouth.
Then a foot looms over you, this one tipped with a stiletto heel. You know there’s no dodging it, and you can already picture that sharp heal spearing you like a skewer. Thoughts and words fail you, which is probably for the best since you don’t want your last words to be “heyisthatafootohitisohfu.”
“IT’S STILL ALIIIII-” The girls stop moving, and for a moment you wonder if you’ve died. Is this it? Game over? You tremble and look up to the heel in terror, too shocked by the prospect of your death to notice the new arrival before it’s too late.
A pair of slender fingers grabs your tail, and you squeal as you’re lifted face-to-face with the person you want to see both most and least right now. You can’t really make out her features, especially since as a mouse you can barely squint, but you’re sure you see overwhelming concern written across them.
“Don’t scare me like that again!” Caster chides, dropping you into the palm of her hand. It’s crazy. Just the other day you dreamed of that palm caressing your cheek. Now it’s twice as large as your body. You curl your tail and twitch it idly, doing your best to look remorseful.
“Master, this is temporary. I need to protect you, and that means that I need to always have you close at hand.” Caster politely waits for you to respond.
“Squeek.” You manage, not able to comprehend her reasoning in the slightest.
“I’m glad you understand.” She beams, before bringing you close to her cheek. Instinctive fear floods your little veins as you realize she’s big enough to eat you, but to your delight she instead gives you a fond nuzzle.
Then, to your greater delight, she immediately deposits you in her cleavage. It’s warm, pillowy soft, and perfectly delightful for your furry body. If this is what she meant by keeping you safe, you suppose that you could get used to it…
“Of course,” she continues, and you can feel the vibration of her voice through her breasts, “I also happen to need you as an animal for other reasons. You see… Transformative magic works best when broadcast through an animal host.”
So, that’s her game. Your small mouse body swells with pride as you realize she still fully plans to win the Holy Grail War. With this magic at her side, she’s surely indestructible. Little do you know, she has much, much different plans in mind…
