ハズレスキル『ガチャ』で追放された俺は、わがまま幼馴染を絶縁し覚醒する　～万能チートスキルをゲットして、目指せ楽々最強スローライフ！～

Crest was born as the fifth son of a duke. However, as the fifth son, he was in no position to talk. His childhood friend and also his fiancée, Ellis, treated him just like a slave. And on Crest's coming-of-age ceremony, he received a skill called "Gacha." Yet, he wasn't able to learn how to use it and was banished away from his home. Banished into the forest full of monsters, Crest began to understand the power "Gacha." And then, Crest made up his mind. He will definitely survive and get back on his feet.
