An assassin who belongs to a group only known as the Organization performs his last assassination, and winds up being reincarnated into a new fantasy world with one job - to kill the hero.
 

 

 
I've watched the first two episodes, it's actually dubbed into English as well as other languages.

It's a decent story and I like progression isekai so I enjoyed it but it's also an annoyingly terrible execution of a harem. All the characters are flatter and more unbelievable than a million dollar bill.

I quite enjoyed the LN, but I must say that I agree with @Momogari. The progression jumps around, and the characters are unbelievable. Episode 6 gave me hope that we were going to get some decent plot lines, and then it was all remedied with the wave of a hand and everything is sweetness and light. Years of sexual and physical abuse forgotten in a fairy tale ending.

We'll grant you 6 of these magical abilities, but we should warn you the hero has 30.

Just how did this hero come to be?

Others besides our assassin have come to this world, too. At least the samurai is trying. Sixth episode is very sad, but not unexpected. Still, I'm surprised there's any nobles still left in this world.

I'm up to Episode 9 and he has started assassinating people on his own. Some developments on the romantic front as well.

Finally got to the end, and it was quite a satisfying conclusion (unless you have read the LN like I have) until the twist in the after credits.

So I should watch this?
