After Etherius Thor Dragneel learned Dragon Slayer Magic, he unexpectedly ended up in Windmill Village in the East Blue, where he became sworn brothers with Luffy, Ace, and Sabo. However, he ultimately chose to set sail with Luffy and began his adventure to become the strongest person in the world.

Nami: I love Thor the most!

Robin: What a bad guy!

Hancock: This is the legendary wedding!

"A Certain Magical Index, A Certain Magical Index, who is the strongest person in the world?" "@＃￥%*！..." [Mahoutsukai no Yoru → The Fourth Cup War → Re:Zero → High School DxD → Gensokyo → Little Garden → Cinderella → Type-Moon → No Game No Life (Prequel) → A Certain Magical Index] [Xia Mo]

Two years ago, Yoru transmigrated to the western continent of the Fairy Tail world and activated the attribute-collecting system.

Whenever a mage casts a spell, the system will drop magic power and magical attributes.

Ding! Congratulations, host, you have gained the Time Magic attribute.

Ding! Congratulations, host, you have acquired the Flame Dragon Slayer Magic attribute.

Ding! Congratulations, host, you have gained the property of materialization magic.

…

Two years later, Yoru arrived in Ishgard with Irene's additional magical attributes, Neinhardt's materialization magical attributes, and Brandish's shapeshifting magical attributes.

When Ye Yu activated Brandish's shapeshifting magic, Mira, Erza, and the others exclaimed: Wow, it's huge! ...

Transmigrating into the world of anime, where everyday anime abounds, Masugi Mori thought he'd just begun his career as a plagiarist, but... the infinite stream has arrived. Do you want to understand the meaning of life? Do you want to truly... live? Masugi Mori: ...The plagiarist's plan for a business collapsed midway through, leaving him with no choice but to forge another unparalleled path. Kitagawa Umi: "Mori-kun, I think I've really fallen in love with you." Kato Megumi: "If I could go back, I'd let you..." Shinomiya Kaguya: "Why haven't you confessed to me yet?!" Yukinoshita Yukino: "You're actually looking for my sister again? Are you that into older women?" P.S.: A refreshing read, not a sanctimonious one.

[Campus-like story + counterattack of the top student + growing male protagonist + multiple cycles + single female protagonist]

On the day of the 100-day oath-taking ceremony, the poor student Fang Lisu got stuck in a time loop.

Whatever happens on this day will be reset on the next day.

Only his experience and ability will be retained.

Others keep repeating this day,

He has unlimited time and unprecedented life experience:

[You memorize the vocabulary list 300 times, unlock the ability: <Thesaurus Decoding>]

[You solve 5000 math problems and get the achievement: [Prince of Mathematics]]

[You do 20,000 push-ups and develop a physique: [Perfect chest muscles]]

...

When the timeline returned to normal, Fang Lisu's transformation impressed everyone...

"You were just a poor student yesterday, how come you have reached the highest level today?"

Fang Lisu raised the corner of his mouth slightly: "Maximum level? No, this is just the beginning."

He stepped into the time loop again,

Overcoming global medical challenges, developing controlled nuclear fusion, and winning the Nobel Prize...

During that period of growth that no one knew about, he created infinite possibilities! ~

Seimei woke up to find himself transported to a world of anime and manga. Good news: he was also bound to a system essential for any transmigrator. Bad news: this world wasn't just infested with evil spirits and monsters, but also with various urban legends, like the Slit-Mouthed Woman, Sadako, Kayako, and Hanako in the Toilet… However, thankfully, after binding with the system, Seimei became a legendary Onmyoji. He not only possessed powerful abilities but could also summon various shikigami to fight for him! His goal was to become the strongest Onmyoji and, at the same time, build a grand empire! …Yotsuya Miko: I only feel safe when I'm by Seimei-sensei's side. Ebina Nana: Seimei-sensei, please don't do this here… um… Kasumigaoka Utaha: Hmm~ Seimei-kun, do you prefer white or black? Nakiri Erina: Now it's my turn to taste you. Kirigaya Suguha, Asuna, Shinomiya Kaguya, Fujiwara Chika, Eriri, Suoh Yuki…

Starting in kindergarten, I met Yukinoshita, Hayasaka Ai, and the Kotori sisters... [Male protagonist, multiple female protagonists, daily story] Good news: I was killed by a dump truck, but I traveled through time. Bad news: I traveled through time as a five-year-old. —My name is Gen Chiye, and I'm currently in the last year of kindergarten. Although my body has shrunk, I'm not panicking at all. This is because my system has a "God's perspective." Under certain conditions, I can observe others, defying the laws of physics. Furthermore, I can bind to others. Any power-ups they gain through their hard work will be shared with me. Knowing this, the next step is simple... (This story blends the worldviews of several popular youth anime series, with detailed descriptions of each major character. Even those unfamiliar with the original works can easily read it as an original story.)

Eriri is a childhood sweetheart. Su Xi, who thought she had traveled to the ordinary world, was frantically amassing wealth. However, spiritual energy revived, and worlds merged. Demons, angels, gods, vampires, warriors, and more appeared, creating a magical atmosphere. The Divine Sword of Savior: Whoever draws this sword, undergoing endless trials and surpassing the pinnacle of heroism, will become the savior of the world! Su Xi: Daga, Kongtoalu! [System awakens, triggering a random sacrifice target!] [Sacrifice target - Divine Sword of Savior...] [Congratulations to the host for receiving the sacrifice - the Last King template!] (Initial fusion of High School, Strike the Blood, One Punch Man, Kaguya, Great Teacher, Rascal, Gabriel, Food Wars!

Traveling to the world of Pokémon with an unidentified system, Aisha's initial Pokémon was just a green caterpillar.

What can a green caterpillar do?

Ai Xia: "Unless it evolves, it can become a Liekong Sitting ......"

[Ding, System Quest Released: Harness the Fierce Sky Seat that evolved from the Green Caterpillar to defeat the resurrected Groudor and Gaioka, and reward the Green Caterpillar for opening the evolution route of the Cracked Sky Seat. Aisha:

"?"

Since then, his path as a trainer has been soaring in outrageous directions.

The dragon slayer warrior Mariluli who pressed the dragon attribute first-level god to fight.

The world's No. 1 fire-breathing dragon with Arceus' fireball slate.

Bankilas, who can compete with the original Groudador......

He himself seems to have become magical with the help of the system.

Leshiram: "Do you recognize the beauty of the White Hero Esher?"

Sword King Cangxiang: "He can carry a sword to cut down Wuji Taina with a sword, so what do you want me to do?"

Hoopa: "As soon as the beasts I summoned saw him, they all surrendered to the enemy, this kid is simply a Pokémon succubus!"

However, it seems that Pokémon are not the only ones who are charmed by him......

"If avoiding desire-driven incidents is too difficult, then release those desires and find ways to fulfill them. Of course, mishandling things might lead to getting 'knifed,' schemed against, or thrown into a battlefield of love—but as long as you survive, there's always a chance to turn things around."

"Be meticulous in your conquests, stay true to your character, leverage every advantage around you—and don't panic when faced with the occasional bad ending."

"Winning hearts is troublesome work, but having a reference target makes it much easier."

Xiao Baiye glanced at the scene in his living room: Kasumigaoka Utaha, Sawamura Spencer Eriri, and Kato Megumi all petting the poor, overwhelmed orange cat together.

Maybe his conquest wasn't going so badly after all?

Now, what should he do tonight...?
