Rano Nakamura, a 17-year-old otaku, lived his life normally—going to school and spending his days watching anime.
His life was always peaceful, but also quite boring—until one day, everything changed.
As he walked through the streets after school, a mysterious light suddenly surrounded him.
Rano: "What is this?"
He was completely startled by the light.
When he realized it, he was in a strange medieval city.
Rano: "What is this weird pce? Why is there a medieval city here??"
Looking around, he saw strange houses and shops, people dressed in old-fashioned clothes.
Rano: "What kind of pce is this? This is really strange!"
Rano wandered aimlessly, hearing people talking and noticing other unusual things.
Rano: "Wait a minute, I got it!! I was summoned to another world to save them from some threat! But I haven’t seen anyone since I arrived! Who could have summoned me??"
As he walked through the streets, unsure of what to do, a loud roar suddenly echoed throughout the medieval city.
Rano: "What was that? What's happening? What was that roar???"
Suddenly, people started running and crying, panicked. Then, Rano saw a man and five strange creatures with him.
Rano: "What the hell is this? What are those things??"
The man standing with the creatures suddenly spoke.
Mysterious Person: "HAHAHA! Allow me to introduce myself—my name is Timo Mont, a 350-year-old researcher. And well... it's about time you all paid for what you did to my parents. So now, SUFFER! THIS USELESS WORLD IS WORTH NOTHING!"
The creatures following Timo Mont began attacking everything in their path—people, buildings, everything.
Rano: "Pay for his parents?? What does he mean? It doesn’t matter! I need to get out of here!!"
In a desperate act, Rano ran toward the first forest he saw.
As he ran, he suddenly tripped over something.
Rano: "Ouch, what was that? Why did I trip??"
Looking down, he saw a sword with a strange stone embedded in its center.
Rano: "Is this... a sword?"
He picked it up and examined it closely.
Rano: "There’s some kind of strange stone in the middle of it..."
Rano: "Well, I might need this. I'll take it just in case..."
Wandering without direction, not knowing what to do in this world, he suddenly heard a female voice screaming for help.
Rano: "What was that??"
Following the sound, he soon found a girl with red hair and blue eyes chained to a tree.
Rano: "Huh??? Why is there a girl chained up here?? It doesn't matter now, I need to help..."
He approached carefully to understand the situation.
Rano: "Hey, you!"
The girl responded.
Girl: "Who are you?? Please don't hurt me! I won’t resist..."
Rano: "Resist? Hurt you? Why would I do that? I just want to understand why you're chained up and crying for help."
Girl: "Some strange monsters killed my father because they wanted the location of a powerful artifact capable of destroying this entire world."
Girl: "My father refused to give up the artifact and was killed right in front of me. Then, they chained me up after I also refused to tell them where it was... They’ll kill me if I don’t reveal the artifact’s location..."
Rano: "Monsters? Artifact? W-what do you mean?"
Girl: "I'll expin everything ter, but please help me get out of here if you really don’t mean any harm."
Rano thought to himself: What can I do to free her???
Then, he remembered the sword he found and got an idea.
Rano: "Look, I can try to break this lock with a sword I found, but I don’t know if it’ll work..."
Girl: "A sword...?"
Rano took out the sword and struck the chains with great force. Suddenly, the sword released a massive surge of energy, completely shattering the chains and sending Rano flying backward from the sheer power that erupted from it.
The girl was amazed by the sword but quickly rushed to check on Rano.
Girl: "That was incredible! Are you okay??"
Rano: "Oww... What was that? That strange energy coming from the sword was completely unexpected..."
Girl: "I've never seen anything like that either..."
Rano: "That was really weird... Anyway, what's your name?"
Girl: "Oh, I didn’t introduce myself, did I? My name is Alisa Mayka, I'm 17 years old. And you?"
Rano: "I'm Rano Nakamura, also 17."
Alisa: "Rano Nakamura? That name sounds unusual... Are you from another country, or are you from Hima?"
Rano thought to himself: Hima? So that's the name of this country in this world...
Rano: "I don't even know, to be honest..."
Alisa was confused but didn’t ask further.
Alisa: "Rano, we need to leave here quickly. The monsters will return soon, asking about the artifact. I don’t want to reveal its location. My father told me I can’t tell anyone."
Rano: "Okay, I get it, let’s get out of he—"
Monster: "Where do you think you're going?"
Rano turned around and saw one of the creatures he had seen earlier, but this one looked different.
Rano: "Who are you??"
Monster: "That doesn’t matter. Hand over the girl, or you’ll regret it."
Rano stepped in front of Alisa and raised his sword.
Rano: "I’m not handing over anyone."
Monster: "Then prepare to die!"
???: "Die? You're not killing anyone."
Monster: "Huh?"
Suddenly, someone appeared behind the monster and sliced it in half.
Rano: "What???"
The mysterious person stepped forward.
???: "Are you two okay?"
Alisa: "Ah, Mitsuki! I can’t believe you showed up!!"
Rano: "M-Mitsuki??"
Mitsuki: "That’s me, Mitsuki Kaikou, the hero of Hima. You don’t recognize me, young man?"
Rano: "No, actually, I don’t."
Mitsuki: "What? I’ve been the hero here for over five years!"
Rano: "Well, that doesn’t matter now. What are those things??"
Mitsuki: "It looks like that crazy Timo Mont revived those monsters using super-powerful jewels. And now he wants to destroy the world for revenge because his parents were sentenced to death after accidentally destroying a vilge..."
Mitsuki: "But that was just a minion. The real monsters are much harder to defeat."
Rano: "Well... Thanks for saving us..."
Mitsuki: "What are your names? I haven’t asked yet."
Rano: "Rano Nakamura, 17 years old."
Alisa: "Alisa Mayka, also 17!"
Rano: "You know, Mitsuki, I found a really strange sword. It has a hole in the middle and released some kind of energy earlier."
Mitsuki: "Let me see that sword..."
Rano showed the sword he had found to Mitsuki, and Mitsuki was shocked.
Mitsuki: "No way!!! The Guardian Hyro's Sword!!!"
