Right now, I just want... to live as long as possible...—Mon-chan, Chapter 114
Shimon Masaaki (子門 真明 Shimon Masaaki), also known as Mon-chan (モンーちゃん Mon-chan), is a supporting character in the 20th Century Boys series. He was part of Kenji's Youth Group and later Kenji's Group.
Appearance[]
As a child, Mon-chan had very short dark hair with the sides of his head partially shaved, sporting a fade of sorts. He was shorter than some of his peers, and he usually wore standard clothes such as buttoned-up shirts and shorts.
As a grown adult, Mon-chan has the same hairstyle save for the front of his hair, which is now slicked back, and his sideburns, which now grow into his cheekbones. He has strong facial features, namely his big nose and small eyes. He is seen wearing a formal shirt and a tie covered by a dark trenchcoat.
In his last years, Mon-chan was noticeably skinnier.
Personality[]
As a child, Mon-chan was a vigorous but easily scared boy, as seen when he asks Donkey to turn on the pump at the school fishtank at night in his stead. He seemed to like playing with arcade machines at the bowling alley and not much is known about his scores at school.
As an adult, however, Mon-chan is much more confident and mature. He still retains part of his child self as he can still be pushed back by scary situations, but he doesn't let that win him over. Mon-chan was also very thorough, and he even managed to acquire important information before his passing in 2002.
Biography[]
Childhood[]
Mon-chan loved to play with Kenji and his friends. It seems that he was closer to Konchi since he was seen more often with him than Kenji, Otcho, Yoshitsune, and Maruo in flashbacks. It was with Konchi, along with Keroyon, that he asked Donkey to go to the science lab for him. The three of them were witnesses to Donkey's impressive jump from the school's higher floor.
Adulthood[]
Mon-chan visits Sadakiyo.
After moving to Germany, he became involved in rugby, a sport in which he excels. However, his mother fell sick, which led him to the decision of stopping his rugby career. He cared for his mother and was dedicated to his work. He was doing very well, but his mother died eight years later. It was then that Mon-chan decided to start his own business with a colleague.
Mon-chan's first appearance.
In 1997, while his business was booming in Germany, Mon-chan still returned to Japan from time to time to meet up with his childhood friends. In 2000, before responding to Kenji's call, he found out that he was suffering from an incurable disease. On December 31, 2000, or the Bloody New Year's Eve, he was just as terrified as the others. Still, he managed to survive.
Last years[]
In 2002, he is nailed to a hospital bed as his illness has reached a critical stage, and Yukiji checks up on him regularly. Mon-Chan reveals to her what he found while investigating; Friend's organization, excerpts from the "New Book of Prophecy", predictions, etc. But shortly after this talk with Kiriko, Mon-chan left the hospital without informing Yukiji. He manages to find Sadakiyo, to whom he asked the identity of Friend, his plans and his accomplices.
Mon-chan, however, is killed by his "old friend", who steals his memo containing all the information he gathered. Yoshitsune and Kanna learn about this in 2014, and even if they suspected that his illness would get to him one day or another, they are devastated.
