beginner package winner

My name is Akira Yano. I have an average face. My study is so-so. My physical activities are neither good nor bad. I am an ordinary 17-year-old high school student. And yet… I’m in an empty, blank room right now. Where am I? I’m sure I was sleeping at home. After a while, a light suddenly appear and it shines strongly. “Pow pow pow! Yoo-hoo! It’s the goddess~ Congratulations! You’ve been chosen to be summoned as the hero~!” What is it? Is this a gal-like goddess…? I was suppose to be chosen as a summoned hero by the clumsy goddess, but I was immediately transferred back to my original world due some mixed up on her part . But the “beginner’s pack” blessings that I received were still remained. Huh? In the other world, it’s a beginner’s pack, but in the modern world, it’s an unbelievable cheat, isn’t it? If I use this well, I will be a winner in life, right?
