In a Crossover World, I Summon Saitama as a Heroic Spirit From the Start

Lin Ye: "I was promised I'd be Saitama's disciple, but I can't even pull off a combo when fighting monsters."

When ordinary shut-in Lin Ye accidentally transmigrates into the One-Punch Man world, he thinks that becoming Saitama's disciple and mastering the Way of the Fist will let him rise to power in no time. But no matter how hard he trains, he can't even come close to the slap Saitama once threw. Then one late night, on his way home, he encounters a Seaweed Monster and awakens the Myriad Worlds System...

Kiritsugu Emiya: "Watching him sit so casually in his chair, I have the strange feeling he could tear the Holy Grail apart at any moment..."

Naruto Uzumaki: "That guy used Multiple Shadow Clone Jutsu on me, and I couldn't even make out his face!"

Monkey D. Luffy: "Bro, I said I wanted to drift at sea, but he insisted on punching me ten times first."

Gon: "You mean he fought nine of you at once? Did you hear that right? He really hit me nine times in one minute!"

Chrollo: "He can read my Nen abilities instantly, so I didn't even get a combo off."

Lin Ye only wants to complete the System's missions and break through his limiter. "Why do I have to follow the System's procedures in every world, only to be told that my stat points and skill books are crooked methods?"
