Makikomarete Isekai Teni suru Yatsu wa, Taitei Cheat

Synopsis

One day during lunch break, high school student Yuzo Ogata was transferred to another world of sword and magic together with four other friends (two handsome males, two gorgeous females). According to the magician princess of space-time, this foreign world summoned them to defeat the demon king. The four friends were surprised and disoriented, but... "There should only be four braves though?" Summoned by mistake, Yuzo is unsure what awaits him in this world... The non-hero uses cheat-like skills to gain a harem and become the strongest in this "ultra"-righteous (?) fantasy! (Source: Takarajimasha, translated)
