In his previous life, Lu Xia unexpectedly obtained a Xuanwu pendant. He thought it was a fake, but it turned out to be the real deal. So, out of desperation, he had no choice but to take it with him and was forced to travel to the world of Quanfa.

However, during the awakening of magic, an unexpected event occurred, and he actually awakened the water element, one of the three useless elements in the early stages.

Lu Xia initially thought he could only stay behind the scenes, but after unleashing his magic, he suddenly realized how short-sighted he had been. Who says water-type characters can't be main damage dealers?!

Facing the group that had looked down on the water element in the past, Lu Xia only had one thing to say: "Try hitting me once!"

Years later, facing an overwhelming army of demons, Lu Xia only said one sentence: "Who dares to strike my shield!"

"What? You're saying everything will be fine if you don't hit me?"

"Hilarious! Magic changes in an instant, why can't I take the initiative to attack?"

This book is also known as "I Play Shield Counter in All of France", "With 100% Counter-Thrust, I'm Invincible", "I Wear Thornmail in All-Round Mage", and "Who Says a Defensive Mage Can't Carry?"

P.S.: While ensuring the protagonist's safety, try to salvage all the tragedies in the original story that can be avoided.

Natsukawa Sousuke unexpectedly transmigrates to Sakurajima, hoping for a peaceful life of joining clubs and enjoying his youth. However, fate has other plans; without inheriting any of his memories, he only has enough money to live on for a month. Fortunately, every cloud has a silver lining. Just as he was considering whether to try his luck at a convenience store part-time job...

On the app called FreeFriends, he met Saki Kawasaki, a woman short of money due to a family change. On the train, he encountered Kotonoha Katsura, a cowardly girl who was bullied at school. He became a model and met Kirino Kousaka, a girl who loved the anime. From that month on, Yuu Kasugano's youth was no longer normal.

Lin Jin, who transmigrated into the world of Detective Conan, discovered something amiss with his dreams. In one dream, he unleashed a barrage of attacks on Ran, but the next day, she lost her match due to a muscle strain. He dreamt that Eri Kisaki was investigating a case of female assault, and he offered to help, cooperating in reenacting the case, which gave Eri a breakthrough the next day. He dreamt that he trained with Sun Wukong, and the next day he had eight-pack abs. "It's a pity dreams are random, otherwise…" Lin Jin felt quite regretful. If he could, this thing would be far more useful than time stop.

In Class 1-A of Tokyo Advanced Nurturing High School, there was a student who became the talk of the school from the very first day. He was effortlessly cool, even doing his cleaning duties, eating lunch, and standing as punishment in the hallway. Every move he made exuded—Cool! Cooler! Coolest! This student, who embodied coolness and elegance to the extreme, was named—Sakamoto. He casually pushed up his glasses: "I am Sakamoto. What brings you here?"

He transmigrates into the world of Kuroko's Basketball, carrying a skill proficiency panel, only to find himself in the world of Prince of Tennis, Akutsu Jin. This time, he will not waste his body's talent and is determined to reach the top.

"Genius? Miracle? Chosen by God? Ha, those are merely the threshold to seeing me." After saying this, Akutsu slowly raised his head, his eyes flashing with electricity, and several phantoms in different poses appeared around him.

Chihaya Himegami couldn't understand why her mother insisted she attend this meritocratic school and even brought her a maid. What puzzled her even more was why her admission documents listed her gender as female! And what baffled her most was why girls still wanted to date her even though she was dressed as a woman! Hayasaka: That being said, Onee-sama, the head of the family didn't ask you to have a harem here.

[Orange] The last guardian of the world—Haga Mayumi—after the destruction of her world, finally broke free from the trap of immortality and entered into eternal slumber. However, when she opened her eyes again, she was reborn in another world. This world is strange. The guardians here don't get hurt or bleed, and they don't get covered in dirt like she does in battle. They always have sparkling magic to keep their clothes clean, and they can fight and fly in light dresses without revealing anything. Those guardians with brightly colored hair and clothes are called "magical girls," and it is said that no one knows their identities. Even though Haga Mayumi's childhood friend, classmates, transfer students, school doctor... and even the idol girls she saw on TV all have unusually bright hair, and each one corresponds to the hair color of a magical girl, no one notices anything unusual. It's outrageous. However, she doesn't know that the most outrageous thing in this children's world is herself—she can bleed, can move freely again in three minutes after a severed arm is stitched back up, and can resurrect from a state of minced meat after exploding into orange juice and splattering people's faces.
