Dying trying to rescue his fellow students from a fire, Shirou ends up in another world with those that didn't make it. Given the abnormal class of 'Sword' he has to survive and find a way to help uncover the mysteries of this world. Problem is, he's a utility class, not a fighter. (Fate X World Strongest Rearguard)

Did Shirou have a clue what was going on? No. Not really. But that was nothing new. In fact, all of it seemed oddly familiar. Everything was the same, from the hole in his chest, to the black haired girl with a glow red object. Now he was involved in a war that previously had nothing to do with him, with the fate of the world hanging in the balance. So you know, same old same old.

After his passing, Technoblade finds himself in Melromarc as the 'Hero of the Sword'. Those poor fools had no idea what they had just done. (R.I.P. Technoblade)

Shirou Emiya had not been ready for the Clocktower. He lacked roughly seven years of the background required to do anything of value there, and the attempt to teach him was cutting into Rin's own research time. So Zelretch decided to send the boy away to another world to complete his 'magical primary school education'. Not like he has the power to say no.
