Sen no Skill wo Motsu Otoko: Isekai de Shoukanjuu Hajimemashita!

A newlywed man, bored by his wife's absence, daydreams about a peaceful ski vacation. In this imagined scenario, things take an unexpected turn. Still within the dream, he passes through several doorways and suddenly finds himself rescuing a female knight from a large spider. He learns he has been summoned to another world as a summon beast, a type of assistant that can be transferred from his world to others. Through completing these summoning tasks, he can acquire magical abilities. Having no particular talents in his original world, this development could be the most fortunate event of his life.
