The Average Isekai title: My Best Friends Abandoned Me in The World's Worst Restaurant Chain, So I Devised A Fool-Proof Plan to Feed Their Entrails to The Stoned Monster in My Attic
The longest titled one I've watched so far is called 'My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me!' although this is still pretty short compared to some others I've heard of before
I mean the hardest title i've had to say was "The Tsuntsuntsuntsuntsuntsun tsuntsuntsuntsuntsundere Girl Getting Less and Less Tsun Day by Day" seriously it's difficult to say "TSUN" so many times in a row in rl
