200 YenEdit

A 12 year old Saitama is dozing off during his middle school opening ceremony. Later, Saitama is relaxing in his bed watching a news report about an escaped mysterious being. Soon after, a teacher berates Saitama for not doing his homework, and tells him to meet him in the teacher's lounge after school. After school ended, Saitama is accosted by the two delinquents known as Ripped Uniforms. The two drag Saitama out to the school yard and ask him for his money. Saitama refuses and then prepares to fight them, but gets easily beaten up and his money, 200 Yen, gets stolen.

Piggy Bancon shows up and takes all the money the two delinquents had, including Saitama's money, then runs away. Saitama gets up and chases after the monster. He catches up to it, but gets knocked out for at least an hour. He then shows up at the teacher's lounge, beaten and his uniform torn apart, and gets shouted at. After leaving the teacher's lounge, he starts questioning his future. The scene then jumps forward in time to Saitama carrying a child on his shoulders on a snowy hill, having just defeated a snowman monster. The child then asks if Saitama can beat up another snow monster, this one being significantly larger. At this point, Saitama realizes he forgot to take out the trash.[1]

Brushing UpEdit

During Saitama's training days where he was aiming to become a hero and had hair, Saitama saved an old lady from a mysterious being. He is rewarded with a year worth supply of candy. Afterwards, Saitama thinks of how he has taken down over 10 mysterious beings since he became a hero for a hobby, how he is not doing it for the gratitude, and how he has been pushing his body to the limits.

On his 300th day of training, Saitama starts to feel an unbearable stinging pain. As he does his daily jogging, he starts moving at high speed, and thinks of how he is gradually getting used to the training, and how it even gave him a boost in his physical fitness. Saitama shows what he can do by saving a child from a speeding car, crushing its hood in the process. Saitama disciplines the child about road safety, while people around are awing at his amazing feat.

Saitama punches Personification of a Light Pull Chord

Saitama defeats Personification Of A Light Pull Cord

Continuing his thought of his growth, Saitama claims that he is able to move of how he thought superheroes would, but there is still one flaw to his training; the stinging pain, which became more frequent. A mysterious being then appears, boasting about how strong it is, and destroying a nearby vehicle with rapid punches. Saitama approaches the monster, but is unsure of his success because of all the pain. The mysterious being is revealed to be the Tiger level monster Personification Of A Light Pull Cord, who talks about how he has changed and claims to be a "God" level threat. Personification Of A Light Pull Cord then notices Saitama coming from behind to attack him, and as Saitama is distracted by his stinging pain, the monster punches him through a truck and into a wall. Saitama then thinks he is at his limits, but then sets his sights on continuing, as he did not come so far for nothing. Then, right before Saitama is even capable of returning to the fight, Personification Of A Light Pull Cord attacks him with his Pull Cord Rush. Saitama then appears to be down, and a tooth falls out of his mouth. Saitama then recuperates, much to Personification Of A Light Pull Cord's surprise. Feeling much better now that his decaying tooth is out (which was the origin of his stinging pain), Saitama beats Personification Of A Light Pull Cord.

Back to the original story line time. Saitama is seen leaving the bathroom, after seemingly brushing his teeth, and thinks of how maintaining healthy teeth prevents tooth decay.[2]


During Saitama's first year and a half of training, Saitama is at Z-City's Shelter Nr. 7 hiding from a mysterious being. Saitama then realizes the heroes that were sent to deal with the monster were all defeated, so he attempts to escape, but the other civilians stop him, thinking he has become suicidal. Saitama then notices he has to use the bathroom but cannot find it. He asks a female staff member of the Hero Association where it is, to which she replies there is none, which Saitama states is a huge flaw.

One hour later, Saitama is struggling with his filled bladder. A person on the phone says that the mysterious being's threat level has just risen to Demon, and that they now must wait for the newly formed "subjugation squad", which will arrive in 3 hours. Upon hearing this, Saitama moves rashly and proceeds to punch a hole in a wall, saying that he is going to the convenience store, much to the crowd's surprise. Saitama then runs towards the convenience store, and is interrupted by the Magicicada Nymph, who is swiftly killed by the rushing Saitama.

At the present day, Saitama sees a 170,000-Year Magicicada Adult and notes the arrival of summer.[3]

As Saitama is out on a walk, he is suddenly pulled over by two policemen looking over for any suspicious activity while on patrol. After some discussion, they take him in for questioning. Through further investigation into his background, the two police officers come to the conclusion that Saitama may be the culprit behind a string of grisly assaults that have been occurring around their precinct. While admitting that an unpopular hero is no different than a part-timer, Saitama wonders what the police force's bone to pick with the Hero Association was, before enjoying some pork cutlet offered to him by Chief Kuma. As they Are still conversing, the real culprit behind the assaults appears; a Demon level monster threat named Surprise-Attack Plum. It starts attacking their establishment. With the disaster at hand, Chief Kuma had to be dragged away from the questioning room to observe the threat. Chief Kuma calls the Hero Association out of desperation. The derogatory second chief of operations for the Hero Association McCoy desired his opposing heckler to cast aside his and the face of the police. Saitama quickly snatched away Kuma's cellphone, crushing it before he could voice his humility, clarifying that neither heroes nor cops do their job because people say "I beg you" and that the man on the other end of Kuma's phone wasn't any kind of hero.

McCoy's plan backfires when a lone police officer steps out of the building carrying out the downed creature on his back, much to everyone's shock and awe as well as McCoy's chagrin. All the news channel sponsors present at the scene bustle their way into a police blockade, desperate to know who the mystery officer was that took out the monster attacking them at their office.

After Charanko arrives with the vegetables, they start preparing the hotpot while talking about a recent dojo hunter that has been attacking other dojos. Saitama notices that there isn't any cabbage, interrupting the conversation, which annoys Charanko.

After preparing the hotpot, they hear a loud voice calling a challenge. Inside the dojo enter a large group of martial artists, claiming to be from the "Harsh Path Style" and asking for Bang, master of the "Water Stream Rock Smashing Fist", so that they may crush the dojo. After Charanko chastises them, saying that this dojo does not tolerate dojo hunting, the martial artists challenge him instead and assault him. Charanko tries to call for help, but Saitama and Genos are still cooking the hotpot and are not aware of what is happening. After Charanko is kicked back and almost lands on the hotpot, Saitama catches him using his chopsticks. One of the martial artists sees the lobster and moves to crush it saying that it is a luxury not fitting of a martial artist, at which point Genos launches across the room, saving it. When the group tries to attack, Genos knocks one of them through the wall with a single push, leaving a hole in the wall. Saitama praises Genos, saying that while it might not be their job to subdue dojo hunters, these ones had crossed the line, at which point they try to attack him. Saitama quickly grabs and throws all of them using his chopsticks, leaving several more holes in the wall. After Bang arrives, he seems rather upset about the condition of the dojo and asks the last remaining member of the group if they had done it. When the guy tries to say it was Saitama and Genos, Bang angrily says that they are the ones picking a fight here. After the group leaves, Saitama is seen enthusiastically enjoying the hotpot.[10]
