Higashikawa Mamoru
Prepare yourself. This will be the last attraction. I don’t care about the Unbeatable Emperor or the Ever-Victorious Challenger! I will destroy all of your plans here!!
~ Higashikawa Mamoru to Karen


Higashikawa Mamoru is the main protagonist of A Simple Monitoring. Mamoru is an university student who, looking for a way to get some money, took a part time job in an amusement park known as Attraction Land. His job was simple, to watch videos about future attractions to monitor them and find imperfections and flaws that needed to be corrected. However, the videos turned out to be far darker and gruesome than he expected them to be, and after losing consciousness, he found that he and the other applicants to the job had been trapped in an insane death gambling game by a mysterious group.

Notable Attacks/Techniques:

  • Ever-Victorious Challenger: The absurdity gained by Higashikawa Mamoru at the end of the gambling games. Mamoru acquired the character of the Ever-Victorious Challenger, the special participant of a gambling story who never loses. Without even needing to do anything, Mamoru can call in an infinite supply of success, something Karen compared to being a deity of victory. Because of this, Mamoru can't lose any kind of luck-based gamble, no matter if the odds are one in a million, one in a billion or even worse; he will succeed with ease as long as they're not zero. The enemy attacks will miss and fail to harm him, the ground will break beneath the enemy's feet, their weapons will break mid-swing, etc. When he and Karen (who had gained a similar absurdity) fought, they realized it was impossible for them to kill each other, as their weapons constantly broke when they tried to attack the other person. Karen further stated that even if they brought a gatling gun or a shoulder-fired missile to the fight they would still be unable to harm each other. This absurdity can also be used outside of battle, such as to deactivate a bomb by randomly pulling the correct wire or to successfully guess a password in your first try by typing at random. Additionally, as Karen pointed out, Mamoru's absurdity works outside the constraints of time and continuity/causality, as he was capable of using it to undo the past event that had granted him the absurdity (ignoring time) and he retained the ability after doing so (ignoring continuity/causality).
