俺の死亡フラグが留まるところを知らない

Isekai into a game world as the villain

The protag isekais into a game world as the villain Harold during his childhood and proceeds to work to avoid the death flags that led to the original villains death. In typical villain isekai fashion this leads to the people around him growing to admire and follow him as to do so he spends his time making things better. One twist is Harold cannot speak completely freely as he is bound somewhat by the original Harold's personality when talking.

So far it hasn't done anything unique but it's entertaining enough I'll keep reading.

For a fantasy the aren't many made up words used so far.
