Ace Cross is not your typical NEET, although he has all the making of one and is recluse, he is still a very outdoor type of person. One day he is killed (by a truck no less even after dodging off the road) his soul was going to white light in the sky (the sun) but before he could arrive a magical circle appears and he is pulled in and given a second chance at life in a magical world under the most cliche trope of anime, as a summoned hero.
