45-sai no ossan, isekai shokan ni makikomareru

Kojiro Shirakawa (45), an utterly ordinary office worker, was commuting by train as usual today… Or so it seemed, but he was suddenly caught up in a mass summoning, and when he woke up, he had been transported to another world! To make matters worse, right after the summoning, a suspicious ritual begins. It turns out he’s in a shady kingdom plotting to steal the skills possessed by Japanese people! Shirakawa finds himself in a dire situation right off the bat, but then something strange happens to his smartphone. When he checks it, he discovers that countless skills have manifested within him, a middle-aged guy!?
