Fate/True Hero: Reincarnated as Saber in Another World

Seiji Sawada is dead. Gone and forever to be missed. The End.

Or it was supposed to be. Imagine his shock when he was unwillingly reincarnated in the body of the king of Britain... And said king is actually a female.

Summary:
Seiji Sawada lives his life as a normal teenager, with no wish for anything special like traveling to a fantasy world or anything similar. Life, however, had other plans. He died and was reincarnated as Artoria Pendragon! And the worst part is that he is now 'SHE'! Now with her slime buddy, They will be on their new journey! Let's see what they encounter in their adventure.
