Toaru Majutsu no Index: Genesis Testament - Volume 1, Chapter 4: Interaction with Another World, the Starting Point — “R&C OCCULTICS Co.Ltd.”

This novel is also known as Only I Level Up

10 years ago, after “the Gate” that connected the real world with the monster world opened, some of the ordinary, everyday people received the power to hunt monsters within the Gate. They are known as “Hunters”.

However, not all Hunters are powerful. My name is Sung Jin-Woo, an E-rank Hunter. I’m someone who has to risk his life in the lowliest of catacombs, the “World’s Weakest”.

Having no skills whatsoever to display, I barely earned the required money by fighting in low-leveled catacombs… at least until I found a hidden catacomb with the hardest difficulty within the D-rank catacombs!

In the end, as I was accepting death, I suddenly received a strange power, a quest log that only I could see, a secret to leveling up that only I know about! If I trained in accordance with my quests and hunted monsters, my level would rise.

Changing from the weakest Hunter to the strongest S-rank Hunter!

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?”

After being set up and killed by her half-sister whom her ex-boyfriend had cheated with, Mu Siyin woke up one day to discover that not only was she alive, but she had traveled back in time to 2 years before her death.
