A System is involved, but it provides no abilities or boosts to combat strength, only external items. A pure swordsman story, with thrilling battles and regrets put right.
(Demon Slayer) (Akame ga Kill!) (The old era of the One Piece world: the Rocks era and the Roger era) (Fox Spirit Matchmaker) (One-Punch Man) (Holy Grail War)
Hawk-Eye Mihawk, who had devoted himself to the way of the sword in solitude, experienced a different kind of life in his castle. He spent two years living with his disciple Zoro and the perpetually lost Perona.
Those days brought color to his monotonous life, and watching Zoro grow made him look forward to what lay ahead.
Two years later, after sending Zoro off, he returned to his old, dull routine, waiting for a swordsman worthy of his full strength to stand before him.
What a long and tedious wait…
Suddenly, an electronic voice rang out:
“Ding! System connection successful! Myriad Worlds Swordmaster System successfully bound!”
“Would you like to meet swordsmen and blade wielders from different worlds?”
“Sounds interesting.”
Mihawk smiled. He packed his bags once more and set off for another world. The world's strongest swordsman's journey along the way of the sword had begun anew!
This is a worthwhile Hawkeye fanfic to read, but there's not much of it right now. You can save it up for a while.
