The Classroom of the Elite: Powered by Black Tech

For some unknown reason, he ended up in a parallel-world Japan and accidentally took over the body of a high schooler-to-be who had died in an accident. By chance, he inherited none of his memories. Yet the first predicament he faced after arriving was... he couldn't understand the language.

Just as he was struggling because he couldn't communicate with his family, a heavenly voice rang out: the black-tech System had activated, and the starter item, Translation Konjac, had been issued.

This is a story about a person with above-average intelligence and almost no fighting ability in a Classroom of the Elite.
