Hataraku Saibou!!

Bump

While chasing a germ that thinks it's cuteness will protect it, White-Blood-Cell-1146 meets Backward-Cap, a platelet training to get stronger. A sudden incident in the temple's area causes a breaking of capillaries, and the platelets must stop the internal hemorrage, with some coaxing from Megakaryocyte (cell that produces platelets).

Acquired Immunity/Peyer's Patch

"Acquired Immunity": Memory Cell receives visions of destruction and believes he has gained the power to see the future. The Parotid gland gets invaded by the Mumps virus. As the immune cells fight them, B Cell cannot create antibodies without Memory Cell's information, but Memory Cell is obsessed with trying to see the future again and is useless. When B Cell strikes him in frustration, he realizes he was actually seeing his memories of the past when the body received a Mumps vaccine. B Cell creates antibodies from the information and wipes out the virus. Afterwards, B Cell explains why it took him so long, resulting in the cells beating Memory Cell up. "Peyer's Patch": U-1146 takes AE3083 and NT4201 on a tour of the small intestine, but Killer T Cell berates him for not focusing on his job. The small intestine gets invaded by Campylobacter bacteria who take an Intestinal Epithelial Cell hostage. The white blood cells surrender and give in to the bacteria's demands to humiliate themselves. However, they were slowly luring the bacteria to a Peyer's patch where the bacteria are ambushed and destroyed. Afterwards, Killer T Cell apologizes to U-1146, but retracts his apology when U-1146 realizes he forgot about AE3083 and NT4201 and rushes over to check on them. (Source: Wikipedia)

Dengue Fever/Acne

"Dengue Fever": The cells complain to Mast Cell when she releases excess histamines for a minor problem and causes inflammation, making her angry and vow not to do her job. The body gets bitten by a mosquito that sucks out several blood cells, then infects the body with the Dengue virus. The virus takes over Langerhans cells and they attack the body. Despite seeing the damage, Mast Cell refuses to release histamines until Basophil tells her to do what she thinks is right. The histamines distract the infected cells and alert the immune cells so they can wipe out the virus. The cells apologize to Mast Cell, but she gloats that she was right all along and did not do anything wrong with her previous histamine releases. "Acne": U-1146 investigates a pore that turned into a pimple and finds acne bacteria have enslaved the hair and sebum producing cells to keep them fed on sebum. The bacteria had also killed several Neutrophils and turned them into pus. A young hair cell almost gives in to despair and says they are only one hair and unimportant, but U-1146 tells him every individual is important. U-1146 fights the bacteria, but their king can regenerate indefinitely due to the sebum he consumes. Drawing on U-1146's words, the child encourages his brethren that they can help by producing an overload of sebum. The king gets so engorged that he can barely move, allowing U-1146 to kill him. U-1146 nearly drowns in the sebum, but survives. (Source: Wikipedia)

H. Pylori/Antigenic Shift

"H. Pylori": Normal Cell, who dreams of saving someone like the immune cells do, finds four cute and tiny bacteria and keeps them as pets. AE3083 delivers oxygen to him while U-1146 detects the bacteria and confiscates them for future disposal just as he is called to the stomach. Normal Cell follows him, worried about the bacteria. The stomach is being attacked by H. Pylori. When Normal Cell saves the bacteria from falling debris, one of them beats up the H. Pylori, allowing U-1146 to kill it. U-1146 realizes that they are Lactic acid bacteria, benevolent to the body. The one that fought stays in the stomach while the others stay with Normal Cell. U-1146 thanks Normal Cell and invites him to join him on patrol. "Antigenic Shift": U-1146 and Normal Cell go to the small intestine, which is overloaded with Purine, but one of the lactic acid bacteria consumes it before deciding to stay there. Later, Normal Cell accidentally drops one of the remaining two into a storm drain. U-1146 sadly remarks that he has no authority over the immune response so he can't tell the other immune cells not to attack that bacterium if they mistake it for hostile, reducing Normal Cell to tears as he insults the immune cells for being heartless. Just then, NK Cell arrives. (Source: Wikipedia)

Cytokines

NK Cell attacks Normal Cell for insulting the immune cells, but U-1146 defuses the situation. Dendritic Cell rescues the lactic acid bacterium that fell into the storm drain and cares for it. The small intestine gets attacked by influenza. The virus has mutated and are unaffected by the immune cells' attacks, causing NK Cell to collapse in despair. The lactic acid bacterium produces Polysaccharides that power up Dendritic Cell and help him produce Cytokines, portrayed as embarrassing photos that shock the immune cells and motivate them to become stronger and wipe out the virus. After bidding farewell to the bacterium, Normal Cell apologizes to U-1146 and gives him permission to take the last bacterium he has. NK Cell informs U-1146 that Cancer Cell has returned.

Harmful Bacteria

U-1146, Normal Cell, and NK Cell go to the large intestine, which is full of toxic gas due to harmful bacteria. AE3083 joins the platelets on a tour of the large intestine. The main Killer T Cell has been promoted to a Memory T Cell and joins them in their search for Cancer Cell. U-1146 tells Normal Cell to go alone and find where the last lactic acid bacterium belongs. Harmful bacteria invade the large intestine, forcing Normal Cell to run while AE3083 helps the platelets evacuate. Cancer Cell ambushes U-1146, NK Cell, and Memory T Cell. They slay him, but it turns out to be a copy. The real one appears and beats them up, saying they will see which of them deserves to survive. (Source: Wikipedia)

Cancer Cell II (Part I)

Normal Cell, AE3083, and the platelets continue to evacuate. Memory T Cell remembers Cancer Cell's techniques, giving his team the advantage, but they are shocked when Regulatory T Cell defends Cancer Cell, believing he is a Normal Cell that needs to be protected. U-1146 is injured and Cancer Cell traps him in a pod, saying he's fascinated with him for the contradiction of being a defender when his function is to kill. Cancer Cell strengthens himself by absorbing the carcinogens in the toxic gas and plans to kill the body so that everyone will be equal in death. Despite hearing this, Regulatory T Cell continues to defend him and effortlessly beats up NK Cell and Memory T Cell. Normal Cell is cornered by harmful bacteria. The lactic acid bacterium tries to defend him, but is swatted aside. Normal Cell orders it to run and it does. The bacteria start torturing him. (Source: Wikipedia)

Cancer Cell II (Part II)

Normal Cell is rescued by the Neutrophils, but they start getting overwhelmed by the bacteria until the lactic acid bacterium returns with its brethren and they turn the tide. With the bacteria defeated, the toxic gas dissipates. Memory T Cell uses his ultimate technique, the T Cell Perforin Cannon Punch. Although it was a made up technique taught to him as a joke, it actually works, firing a beam from his fist that damages Cancer Cell enough that Regulatory T Cell finally recognizes him as an enemy and turns against him. Cancer Cell continues to fight, but without the carcinogens in the toxic gas, he weakens. U-1146 escapes the pod and slays him, with Cancer Cell calling him his friend as he dies. As the lactic acid bacteria repair the damage, U-1146 calls Normal Cell a hero for bringing them. Memory T Cell tries to teach the Naive T Cells the T Cell Perforin Cannon Punch, but cannot replicate what he did. AE3083 catches up with U-1146 before they return to their regular routine.
