My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me! Novel Volume 9 was written by Tsuyoshi Fujitaka with illustrations by Chisato Naruse.

With their intense encounter with Yoshifumi behind them and yet another Philosopher's Stone in hand, Yogiri and Tomochika begin making plans to leave the island of Ent in search of more Sages. However, with the acquisition of another Philosopher's Stone, the infant they were carrying with them has now grown into a three-year-old. On top of reuniting with Vivian, Hanakawa, and many other friends they had thought long gone, there seems to be no shortage of interruptions to stop them from accomplishing their goal. And just in case that wasn't enough, they discover they are now wanted—dead or alive—across the entire world, making their casual journey an even more challenging affair.
