Was there a manga novel where the main character traveled through the magic seal, the Holy Grail, and the object that fell from the sky, with a system, in order to find his own heart?

I Became the God of War, Kratos. This book meets your needs. The protagonist transmigrated to the Holy Grail War World and became the berserker Kratos. I hope you like this fairy's recommendation. Muah ~😗

, I have a few novels here that you might like. They are all works that travel through the Holy Grail World and have a systematic plot. They were "Yuki's Holy Grail Journey","Holy Grail Servant System","Naruto: The Beginning of the Holy Grail War", and "Naruto Holy Grail System". Each of them had their own unique characteristics. They told the story of Yuki, the follower, the protagonist, and Naruto after they transmigrated to the Holy Grail World, and they all covered the elements of the system. I hope you like this fairy's recommendation. Muah ~😗

There were a few novels that met this requirement, such as Sword Immortal who joined the chat group, Infinity from the Giants, and The Final War of the Apocalypse. The protagonists of these novels were involved in the Holy Grail War, but the main content of the novels was not the Holy Grail War. It involved different worlds and storylines. If you're interested in these novels, you can read them. I hope you like my recommendations.

I recommend "Descending from Heaven: Bad Mother Wants to Capture the King" to you. This is an ancient romance novel written by a romantic. The protagonist returned with her cute pet, Meng Bao, after traveling through time for five years. She easily dealt with the ruthless Empress Dowager and her sisters. There were also a large number of scumbag princes who wanted to break off the engagement, but she could easily win him over with a million taels of silver. Playing with beautiful men, abusing scumbags, and living an arrogant life. I hope you like this fairy's recommendation. Muah ~😗

I can recommend the novel "The Invincible Divine Power of Crossing Ten Thousand Worlds" to you. The protagonist has become an invincible existence. He can freely cross ten thousand worlds, possess cultivation techniques, and have a brand new appearance. This sci-fi time-travel novel is similar to the time travel and Holy Grail elements you mentioned. It might suit your taste. I hope you like my recommendation, Mwah ~😗

I recommend "Dimensional Descent Marvel" to you. The main character of this novel is also a male. He transmigrated to the Marvel world and has the "Dimensional Descent System" to carry out various adventures. Although there was no Silver Soul anime, there were many other anime elements mixed in. The Holy Grail War was also involved. I hope you like this recommendation. Muah ~

The main character is an otaku, Chen Xuan. He accidentally obtained the system to extract the myriad worlds of the universe and began to enter different dimensional planes and experience different lives. He also brought the abilities he obtained in the myriad worlds of the universe back to the real world where spiritual qi was recovering and counterattacked all the way! Through hard work, he established his own power. I hope you will like this novel ~ I hope you will like this fairy's recommendation ~😗

There were novels such as "The Scumbag Rebirth System","A Guide to the Sister Who Doesn't Play","A Guide to the Counterattack of the cannon fodder","The Quick Game: A Guide to the Adonis", and "The Quick Game: A Guide to the Adonis Is Too Black-bellied". Their main characters were all reborn into their own bodies and received the strategy system to help them conquer different characters and plots. If you are interested in these novels, you may wish to take a look ~ I hope you will like my recommendations.😗

I recommend to you "The Blade of Pillar Destruction: The Heavens System" and "My Heroic Spirit System." These two novels are about the male protagonist transmigrating to different worlds and possessing a system that allows him to traverse the heavens. Among them, the male protagonist first transmigrated to the world of the Blade of Extermination in the Blade of Pillar Extinguisher: The Heavens System. The world of the Seraph of Eradication, the Index of Forbidden Magic Books, and the Fairy's Tail were also involved. In "My Heroic Spirit System," the male protagonist transmigrated to a world of fantasy and gained the ability to summon heroic spirits to participate in the Holy Grail War. I hope you like my recommendation. Muah ~
