Multi-Mind Mayhem Volume 3

Bard Cornelius is no ordinary nobleman's son; he's a genius isekai inventor. He's got two extra souls packed into his mind: Sanai Oka, a miserly samurai, and Masaharu Oka, a high-school otaku who loves animal ears. Bard continues to churn out invention after invention, earning him huge piles of gold and even the attention of the king. But before too long, villains lurking in the capital stealthily attempt to hinder Bard's progress! As Bard dodges one disaster after another, his rise to the top accelerates, even as he faces political intrigue and a potential pandemic like a cholera outbreak. He must rely on his wit and the support of his companions. Will he overcome these challenges and secure his place in this new world? Perfect for fans of isekai, comedy, and harem stories.
