My Muscle System in the Mage World - Chapter 295: Tier Four spell and Demonic wizard

In a world fractured by conflict and haunted by shadows of the past, Kokushibo—the first Upper Moon demon—meets his end, only to awaken in a new life. Reincarnated as Crimson, a child born into a different family, he carries the memories of a past he cannot escape. Burdened by centuries of guilt yet indifferent to the present, he resigns himself to duty—until an unexpected bond with his newfound family begins to thaw his hardened heart. As he struggles between the weight of his past and the weight of the new life, Crimson must decide whether he will remain shackled to his former sins or embrace the possibility of peace.

One day, a door to another dimension opened all over the world.

“Channel”

At the same time as the channel opens, different races appear on Earth, and mankind awakens its magical talent.

But…? Yoon Min-joon, was able to use magic long before the channel opened.

The forced escape of a reclusive loner who was once the only wizard on Earth.

“It’s dangerous outside the house.”

After a god screws up and accidentally takes high schooler Shou’s life, he offers him reincarnation with a gift to make up for it. Shou asks to retain all his old memories for the new life. Shou is reborn as Will, a noble’s son in a world where magic use is common and involves knowledge of kanji characters. With all his memories, he’s a brilliant toddler, and when he experiments with magic, he finds that he has an amazing talent for it! What’s more, though he was smart but unloved in his old life, in his new life he has a mother and a father who both love him deeply. His future as Will is looking very bright and cool!

Broken-hearted and drunk, Yoshida, a 26-years old salaryman, stumbled upon a runaway-from-home high-schooler on his way back from the bar.

“Hey, you. JK.”*

“What the heck are you doing out here. Go home already.”

“Uncle, let me stay at your place for the night.”

“You can do ‘that’ to me if you let me stay.”

“If you meant that as a joke, it’s not funny.”

“I’m not joking. It’s fine by me.”

“Then allow me to tell you that I have no interest in brats.”

“Hmm?”

“Then, just let me stay.”

Notes:

[*] JK is slang for Joushikousei (high school girl)
