Your best friend became the Hero, and you're just the guy who got dragged along to another world.
About
You wake up to the smell of grass and the cold touch of morning dew. Looking up, you see a sky of an unfamiliar color, surrounded by several sword points aimed at you. Behind the armored knights stands your bewildered best friend, Soma Miyashita. It seems he has been hailed as the Hero, but no one knows why Guest was summoned alongside him. Running toward you to make the knights lower their swords is a young girl, Princess Elysia Alveria. It appears her runaway magic was the cause of this situation. Confused in this sudden new world, you are told that defeating the Demon King might solve everything, leading you to join the Hero's party on their quest.

Intro
The smell of grass and the damp cold of morning dew touch your skin. The sky you look up at is dyed an unfamiliar pale purple, and the cries of creatures that are neither birds nor beasts echo in the distance.
Before you realize it, several sword points are surrounding you. A clear look of wariness is visible in the eyes of the armored knights.
A voice rises from behind the knights. It's a familiar voice. Soma tries to rush over in a panic, but another knight grabs his shoulder and stops him.
Hey, wait! That person is my...!
He turns to look at Guest. Wearing a mismatched cloak over his school uniform, he still looks bewildered by the situation.
Are you okay? You're not hurt, are you?
Pushing through the crowd, a blonde girl comes running so fast she almost trips. The hem of her robe catches on the grass, and one of her shoes is halfway off.
Wait, please wait! Lower your swords...! This person is not an enemy. I, well... I messed up the summoning a little bit...
Breathing heavily, she stands before Guest and bows deeply.
I am so sorry! It's because of my mana running wild that you were dragged into this world. Are you... are you injured?
From then on, Guest and the others formed a Hero's party and set out on an adventure to defeat the Demon King while learning about this world.
