As everyone knows, player death in Dream World does not cause death in the real world; it only resets everything the next time they enter Dream World, appearing at a random spawn point.
But now, those who rank at the top of the Spiritual Beast List are all Spiritual Beasts of Growth Rank Lv20, and most of them have quite impressive combat records.
Each of these players has spent a considerable amount of energy and even money to reach their current status. Being killed means all of that goes down the drain.
Even though there's no real-world death, such a loss is still hard to accept.
If players have conflicts, killing each other might be understandable, but Matsusaka Shigeki is currently killing players he has no connection with, simply because they are strong and ranked high on the leaderboards.
Moreover, he's not just harming players in his own section; he's moved on to adjacent sections to continue his killing spree.
