Entering the next room, Izuku saw a long hallway. As they traversed it, Toriel hummed along with the quiet tune still playing in the background.
"Miss Toriel?" Izuku asked.
"Hm?"
"Do you know where that music is coming from? And… what's up with the music?"
Toriel hummed thoughtfully before her eyes lit up in realization.
"Oh! Are you talking about the room themes?"
Izuku nodded.
"Well, it's been a while since I got the explanation, but I think it has something to do with how magic reacts to the environment. I'm sorry I can't give a better answer."
Izuku smiled, his hand twitching as if reaching for something to write with. "It's okay. When we get to your house, could I have a notebook and pencil?"
"Of course!" she said, stopping before the next room.
"Listen, Izuku, I need you to stay here for a while. I still have some duties I must attend to. Will you be okay waiting here?"
Izuku glanced around the room, contemplating. "That's okay."
"Alright. Here—take this old cellphone. Use it if you need anything or if I take too long. I'll be back in a bit!" she promised, jogging into the next room.
…30 minutes later…
Izuku sat against a pillar, bored out of his mind. His calls with Toriel had been nice—until he heard her phone get snatched by a dog.
Redialing her number, he heard someone pick up, only to be greeted by panting and Toriel's voice pleading in the background for the phone back.
He stared into the next room, a thoughtful look in his eyes. After a moment, he decided: he'd explore the rest of the Ruins on his own.
Stepping forward, he flinched when he spotted the Froggit from earlier.
"Ribbit?" it croaked in confusion.
Realizing he hadn't been attacked, Izuku cautiously approached.
"Ribbit, ribbit!" it said, as a screen popped up beneath it.
"Sorry I attacked you earlier—you startled me. I've got some advice if you're willing to listen. If you act a certain way, or fight until you almost defeat your opponent, they might not want to fight anymore. If a monster doesn't want to fight, please… use some mercy! Ribbit!"
"It's okay. Thanks for the advice," Izuku replied, smiling.
Past the Froggit, he noticed another glowing yellow star. Crunching through the leaves, he approached it. This time, he cautiously reached out, ready to pull back if it hurt, and touched it.
The familiar black-and-white panel popped up again.
Crinkling through the leaves fills you with Determination.HP fully restored!
He felt energy pulse through him, a flicker of red catching in the corner of his eye.
As the sensation faded, a new prompt appeared:
SaveLoad
He pressed "Save." The text turned yellow, a chime played, and the panel disappeared.
Looking down the hall, he continued forward—only to be attacked by another Froggit.
He felt the familiar shift in the air as his soul became visible.
Froggit attacks!
FightActItemMercy
He focused on "Act," which opened another menu.
CheckComplimentThreaten
He quickly glanced over the Froggit. "Um… you have nice eyes?"
The Froggit looked confused for a moment, then blushed.
Despite the compliment, it spat out fly-shaped bullets, each one dive-bombing Izuku. He clumsily wove between them until none remained.
Panting slightly, Izuku noticed the Froggit's name was now yellow. Taking a chance, he selected "Spare."
The air lightened as the Froggit hopped away, still blushing faintly.
Sighing in relief, Izuku moved to the next room. But as he walked down the hallway, the floor suddenly gave out beneath him.
"Wahhhh!" he yelled, landing with an oof in a pile of leaves.
"Oh man… I don't know if my heart can take any more of this," he muttered, clutching his chest in relief.
Looking around, he found a door leading out of the pit. Climbing the ladder, he returned to the upper floor on the other side of the weakened floor.
Continuing on, his phone rang.
Click.
He heard heavy panting on the other end, along with what sounded like rapid footsteps and frustrated yelling in the background. Grimacing sympathetically, he hung up and scanned the room.
A sign on the wall read:
Three out of four rocks recommend you push them.
Izuku spotted the lone rock and the pressure plate nearby. Shrugging mentally, he pushed the surprisingly light rock onto the plate.
Click.
The spikes retracted. "Nice," he thought, heading into the next room.
Beyond the wall, he noticed worn, cracked floor tiles and a hole with a ladder leading down.
Steeling himself, he stepped onto a tile—only to immediately fall through, landing in another pile of leaves.
Dusting himself off, he noticed a leaf path on the floor and a sign.
Please don't step on the leaves.
Rubbing his chin thoughtfully, he nodded as realization struck. Studying the path and the room's layout, he retraced his steps, attempting the puzzle again.
After a few tries, he finally reached the leaves at the top floor.
Didn't you read the sign downstairs?!
He stared at the sign's placement and frowned. "I hope these signs are just being funny," he grumbled, shaking his head.
"YES!" he cheered, finally completing the room and hurrying forward—only to trip over some jiggling blobs.
Moldsmal blocks the way!
Picking himself up, he noticed their names were already yellow. He quickly spared them and continued on.
The next room had more rock switches and a spike bridge. Without thinking much, he began pushing rocks onto the plates—until a voice startled him.
"WHOA! HEY! You can't just push me around like that!"
Izuku yelped, withdrawing his hands and bowing apologetically.
"I'm so sorry! I thought you were just another rock!"
The rock huffed. "Well I ain't. What in tarnation were you tryin' to do, anyway?"
Remembering the puzzle, Izuku asked sheepishly, "Um… could you move onto that plate over there?"
"Hmmm… okay. Just for you, kid," the rock grumbled, sliding onto the plate with effort.
The spikes retracted. "Thank you!" Izuku called as he crossed the bridge.
On the other side, he encountered a tiny ghost hovering over a mat.
You walk into Whimsun's path.
Realizing his mistake, he moved to apologize—but before he could say a word, Whimsun burst into tears and fled.
Feeling guilty, Izuku lowered his head and continued on.
The hallway led to a SAVE point beside a table. Inspecting the cheese on the table, he tried to pick it up—only to realize it was stuck.
Behind him, he noticed a mouse scurry into a tiny hole in the wall. He smiled and touched the SAVE point.
Knowing the mouse might one day unstick the cheese and take it home… fills you with Determination.
A/N
Thank you for your view and power stones, though I don't know what they do.
My brain decided to make this story right when exams are being rolled out, so I will be posting closer to a couple of times a week, hopefully with longer chapters.
I gave up on pat*reon because it was too annoying, so if you want to support me, just use $Cashdreamrr.
Now I want to answer a comment. If you have read Marvel: Game Maker System, that was an inspiration to have Izuku experience the Undertale without adding unnecessary lore or trying to fit magic with quirks. I won't spoil, but you'll soon pick up what I'm putting down.
Thank you again for reading, and until the next chapter!
;D
