Shinwa Densetsu no Eiyuu no Isekaitan - Volume 1, Chapter 3 – Awakening Part 6

Living things really are ignorant – the greed to obtain the key to knowledge and the fundamentals of energy overpowers them. Little do they know that knowledge is full of lies and energy is the root of destruction. Us, mages, have mastered travelling through space and time. We are invincible, we can turn worlds into dust and you, mere ants, will be wiped out with no trace.

-Mage Adam

An A.I.(Artificial Intelligence) gets reincarnated into a world where he becomes a mage.

Traveling through the world of Detective Conan, Chi Feichi was sent to the hospital.

Tuesday.

Doctor: “What day is tomorrow?”

Chi Feichi: “Wednesday.”

Doctor: “Cough, tomorrow is Friday.”

Chi Feichi: “…”

August 21.

Doctor: “What day will it be tomorrow?”

Chi Feichi: “August 22nd.”

Doctor: “Cough, tomorrow is January 1st.”

Chi Feichi: “…”

When everyone thinks that the chaotic time is correct, and one of them cannot correctly identify and integrate into it, then this person is an outlier, a patient!

Once admitted to the hospital, it is as deep as the sea, and it is impossible to recover in this life.

Chi Feichi took a deep breath: “Old! Son! No! Do it!”

I reincarnated as Luna, a supporting character who is accused of ruining the heroine and hero’s relationship, and is mu*dered. I’m not interested in someone else’s man, but the heroine’s friends bully me every day. “Why are you trying to get close to someone who’s already taken?” “That’s right, please stop! Why are you doing this?” “Stop doing such terrible things!” So Luna decides to announce it in front of everyone. “I don’t want someone like Fersen even if you beg me to take him so stop bothering me. I’d rather date Anthes Vincent, who’s rumored to be insane.” And soon she meets someone who she never expected to meet…… “I heard you have an interest in me? The truth is, I do too. Is it a coincidence?”
