Death March kara Hajimaru Isekai Kyousoukyoku

A 29-year-old programmer named Suzuki Ichirou suddenly gets pulled into a fantasy RPG world, where he wakes up as a 15-year-old boy named Satou. At first, he assumes it’s just a dream, but everything feels too real to dismiss. By accidentally unleashing a powerful meteor shower spell—which he could only use three times—he wipes out an entire lizardman army, skyrocketing his level. Now, he decides to keep his true strength hidden, hoping to live a quiet life and make new friends. But with threats like the return of the Demon King looming, his peaceful plans might not last long.
