Just came here to say that yes, the grammar is horrendous. Especially the flow. But, it's his first time and even some of the best tl'ers that I know of literally sucked in the beginning. Even worse then this, to the point it was just barely better than mtl. After keeping at it tho, and with help from the community and others, became a first-rate translator. For instance, Bagleson over @https://bluesilvertranslations.wordpress.com/ was horrible in the first chapters. But later on became one of the best in the community.
If you hate it that much, use your perfect English to edit it for him.
