[System, Upgrade, Treasure Chest, Cheat Code]

Seven Nights transmigrated, and he brought a system with him.

The system has a cute loli voice, but it only urges Qiye to continue getting stronger.

The world of Naruto...

Eye techniques? Bloodline? Summoning beasts?

The system says it has everything, so it's giving the host an enhanced version!

Impure World Reincarnation?

System: How about a permanent control type Edo Tensei card? No side effects!

The world of Douluo Continent...

Martial Soul? Soul Bone? 100,000-Year Soul Ring?

With the system in hand, everything is a piece of cake!

I've heard that the Asura God breaks the law while enforcing it?

System: Host, get the hell out of here!

The rest of the world is still being sorted out...

Nangong Xiao: "I know more about this other world than anyone else." Asuna: "..." Nangong Xiao: "I'm not cheating, really, why are you looking at me like that?" Kasumi Utako: "..." Nangong Xiao: "Who says a cruel other world can't have a normal daily life?" Maple's eyes lit up: "!!" Nangong Xiao: "War is always the last resort. If you play it like a normal card, things will get very..." Shizuka: "Shut up! You're the main DPS, just focus on outputting damage!!" Nangong Xiao: "Ah, oh, coming right now..."

Cheng Feng transmigrated into the world of Fairy Tail. In this world where everyone's combat power is off the charts, Cheng Feng is a little panicked. Fortunately, he possesses the ability to receive magic and also carries a gacha system. With enough money, he can draw cards, and the cards he draws can be used using the receiving magic. This is getting interesting. Paying to get stronger—as long as the money's right, even the Black Dragon will be utterly defeated!

(Don't be so blunt. First, look up why the Uchiha clan was driven to the edge of the village before claiming the Nine-Tails' attack resulted in zero Uchiha casualties.) Liu Yu transmigrated into the Uchiha clan of the Naruto world. Upon entering the world, he faced a difficult choice: choose a useless Uchiha boy or a beautiful Uchiha girl? Liu Yu pondered, "How can I, a seven-foot-tall man, choose a woman?" However… Sett: Constitution Card received. Viper: Summoning Card received. Azir: Summoning Card received. Kayle: Constitution Card received. …So, I'm playing League of Legends in the Uchiha clan.

【Only catch mythical beasts】

Ling Shu traveled through time and space, bringing the 'Genshin System' with him to the labyrinthine city of Orario. "Can I summon weapons and characters I draw in real life?" That's great. But... "Why do I have to choose a villain family to join at the start?" That's a real problem. PS: This is a fanfiction.
