Beastmaster Guy, Kira

It was unknown which world John had disappeared to; even he himself had no idea. But one thing was certain: he had lost 50% of his total power as the price for using a forbidden dark magic skill. In short, not only had his power been cut in half, but his level had also been reduced by half due to the side effects of using it.

You might wonder why John didn't use it from the start, or why he waited until now? The reason was simple: he knew this forbidden spell came with a massive price to pay, and that's why he was reluctant to use it unless it was absolutely necessary or in an emergency. In this case, though, he was very close to dying, so he had no choice but to cast it.

However, regardless of the outcome or the negative side effects, John didn't care—he was just glad to be alive. As long as he remained alive, he believed that with enough time, he could always grow stronger again in the future.
