On the surface, Ryouta Sakamoto, aged 22, looks like the very definition of NEET: unemployed, lazy, unremarkable, and still lives with his mother. In the online gaming world, however, he is famed as one of the best players of "Btooom!", a highly popular game where players throw bombs at enemies and harvest their chips....Until the day he wakes up in a tropical island, with no clue as to how he got there. While wandering around, he finds a man and asks him for help — only for said man to throw him a bomb. Ryouta saves himself by using his gaming skills, even as he realizes that he was just thrown into a real-life version of his favorite game.Together with Himiko, a high-school girl, and Kiyoshi Taira, a real estate agent, Ryouta would have no choice but to try to stay alive — by hook or crook.Btooom! is an ongoing 2009 manga by "Joker" Junya Inoue (of Cave fame), published by Shinchosa and exported to North America by Yen Press. It also has an anime adaptation directed by Yousuke Kuroda as part of the Fall 2012 Anime lineup.It was announced in March 2014 that the manga will be entering its final arc soon.Crunchyroll is streaming the anime. US and Canada viewers may watch it here.
This work contains examples of:
Above the Influence: Ryouta, even though Himiko sort of allows him to in episode 12, ultimately does this. Partly because of he didn't want to be like his former friend in high school Oda, and partly because Himiko isn't still entirely comfortable around men due to her earlier rape attempts.
Better to Die than Be Killed: Taira does this to avoid being eaten alive by the komodo dragons, and partly to not slow down Ryouta any longer after he realizes the latter was still trying to help despite attacking them moments earlier.
Bitch in Sheep's Clothing: In Episode 8, Masahito Date lets Shiki take all the blame for a mess he made in a hospital. However, both he and Shiki later get stuck on the island to play the game, and at first he seems willing to work together. But after they acquire six chips, he attempts to kill her to obtain her chip. While he didn't kill her outright, the bomb did dislodge her chip (along with her left hand), which apparently was technically acceptable, as he managed to get off the island.
When he appears in Episode 9 he is able to trick Ryota and the group for the most part, but his attempt at killing Himiko has let her catch on to him.
Bland-Name Product: For example, the DXBOX 720. The volume covers intentionally look like the covers for video games as well, complete with a CERO rating of "Z" for 18+ (the equivalent of ESRB's "MA").
Body Horror: Miyamoto in Episode 7, after Himiko manages to set off a gas bomb he was carrying on a bandoleer. Its not a pretty sight, and it still wasn't enough to get away from him.
Booby Trap: Since the game is based on using various kinds of explosives and ordnance, this tactic is used very frequently.
Breather Episode: Episode 8 gives Ryota and Himiko a slight breather, and aside from a major scene in the beginning and a Flash Back, nothing much happens.
Broken Bird: Himiko — saw her friends raped, betrayed by them in retaliation, narrowly escaped two attempted rapes... probably the best thing that happened to her so far is meeting Ryouta who happens to play her avatar's "husband".
The Chew Toy / Butt Monkey: poor Kiyoshi Taira is on his way to become one He twisted his right ankle. Then a Komodo dragon, whose bite is highly infectious, bit him and he spent a few days having a fever. Then he had his fingers sliced off by a Knife Nut. All in about 10 chapters.
And then he goes insane from his fever and his homesickness, and tries to kill his companions, only to finally commit suicide instead of mistakenly giving himself over to Sakamoto and Himiko.
Chronic Backstabbing Disorder: Several characters are highly suspicious of each other, largely out of paranoia for this trope should they trust someone too much. Some characters prove they can be loyal, such as Ryouta, while others revel in this trope, such as Masahito.
Cliff Hanger: The anime ends with one. Not only is the story not fully resolved, but it's uncertain if there will be a second season to continue it because it had caught up to the manga (Chapter 50), and considering this is a monthly manga, it's gonna take a long time for enough chapters to be released to animate another season.
Creepy Child: Kira Kousuke, a 14-year-old boy who killed then raped three women. And then, during the game, he just keeps on finding new ways to be creepy.
Dangerously Genre Savvy: When Ryouta first ran into Taira in Episode 3, he's understandably hesitant to team up at first, because it would mean they'd have to kill more people to get off the island. He tells Taira to show him what bombs he has, but Taira tells him if he does that, it'll breed mistrust between them, which would cause problems later. Ryouta thinks about it for a moment, then concludes it's a logical argument, so he joins unconditionally.
Later in the episode Ryota spots a woman getting to a parachute supply drop before him, only to see her get blown up by a trap laid by another person. When Taira catches up, Ryota tells him what happened, and says risking their lives for food isn't worth it. But Taira tells him that if they don't at least try, they may end up facing someone who is fighting on a full stomach, while they themselves are starving, and therefore less physically and mentally prepared to counterattack. Ryota once again agrees and they decide to run towards a parachute drop which doesn't seem to have been spotted yet.
Miyamoto, the muscular guy with the knife, is a former mercenary, so doesn't need to rely on the game's functions as heavily as Ryota does. In episode 7, he uses tracking skills to follow Ryota back to where Himiko and Taira were at, and also uses a knife more than bombs to kill other players with. He also booby traps a door in the event Ryota somehow makes it there, where Himiko is currently being held.
Ryota himself is forced to utilize this trope in order to survive his many fights. Whereas he's clearly no match whatsoever in a straight up fight with Miyamoto, he knows a lot about the game, and utilizes those skills to gain the upper hand during his fight with him in episode 7.
Date My Avatar: Ryota and Himiko's Btooom! avatars are married..., then they fight alongside each other in a real-life version of the game.
Deadly Game: Every person on the island has a gem on their left hand, and the only way to get off the island is to grab seven of them from other people, by killing them. Naturally this causes law-abiding people to be hesitant, while those with lower morals find it easier to use the bombs given to them.
Despair Event Horizon: Ryouta's constant leaving Taira eventually causes the latter to lose his sanity and attempt to kill him and Himiko.
Disney Death: Ryota suffers one in episode 7, after getting knocked off a building and falling down the cliffs. All of the characters there believe he's dead, but he was saved by landing on a sturdy tree branch before hitting the rocks below.
Does Not Like Men: Himiko, before Ryota saved her a few times; then she opened up to him a little
Shiki Murasaki isn't all that fond of men, either. She tells Himiko about it in episode 8, when she was twice betrayed by the same man.
Do with Him as You Will: Date, wounded fairly badly by his own bomb, is at the mercy of Ryouta, and then Shiki says she'll spare him the blood on their hands by killing him. Date then apologizes to her, and despite having a very good reason to kill him, she ultimately chooses to save his life instead.
Driven to Suicide: Ryota's mother slits her wrists after nominating her son for the game, though her husband finds her and calls an ambulance.
G.I.R.L.: Ryota's friend jokingly assumes this in episode 2 when he talks to Himiko in the game.
Hair Color Dissonance: It's either this, or Junya is not the one coloring the covers and promotional material. Ryota has a total clear shade for his hair color in the actual manga, and yet in the color portions his hair is black; needless to say, the colors don't match, there's no way Ryota's paste hair can translated into black for full color portions. It could be white, green, blue or any other clear color that becomes null in Black and White, but not black.
I Know Mortal Kombat: Many characters applied their skill and knowledge in the online game Btooom! when playing its real-life version.
I Was Quite a Looker: Shiki Murasaki She's not even 40 yet, but losing an arm and spending 6 months living alone on the island sure did a number on her.
It's All About Me: Ryouta at first, until he begins to realize that this trope was hurting many other people in his life, such as his mother when she remarried, and he attacked his stepfather without opening up at all to him.
Played straight with Date Masahito.
Killed Off for Real: People who are killed on the island are really dead, something that takes Ryota and the non-insane characters a while to comprehend and accept.
Knife Nut: One of the players, Miyamoto, an ex-soldier who prefer using his knife rather than bombs.
Left for Dead: Shiki Murasaki, who was betrayed by Date Masahito once they got six chips. The homing bomb he used wasn't enough to kill her outright, but it did cause her chip to come off, and he figured she wouldn't survive the massive bleeding from her left arm anyway.
Let's Get Dangerous: Ryota doesn't have too many practical skills outside of games, which hurts him a bit when he runs into opponents who are better trained, such as Miyamoto. However, because he's extremely familiar with the rules of the Btooom game, when he utilizes those skills, he's just as deadly as the person he's fighting.
Like Reality Unless Noted: The series is largely realistic, but a few of the BIMs are beyond modern technology. The Homing BIM is quite advanced, though probably still a decade or two away from becoming real. The BIM that produces flames in an "X" pattern is also something unlikely in real life, though theoretically it could be possible, but the Implosion BIM and the Shield BIM stray right into science fiction territory. The radar chips implanted in each player's hand are also way beyond today's technology. In the manga, the Tyrannos Corporation uses them to gain their accurate video and audio feeds of what's happening on the island.
The Load: Himiko at first, then Taira after he gets bitten by a komodo dragon. The latter ultimately kills himself to prevent this trope from slowing Ryouta down due to his injuries.
Mega Corp.: Tyrannos, the company that developed Btooom! They have their own private island, kidnap dozens of people around Japan and send them over, recruit a team of Private Military Contractors to keep them in line on the plane ride, and arrange for daily supply airdrops over the course of each game. Not to mention some of the BI Ms and the IC Chips are very advanced technology: the implosion and shield BI Ms are things we are not even close to being able to develop in real life.
Miyamoto Musashi: One of the players is a rather less noble fellow named Miyamoto Masashi
Mr. Exposition: Taira fills in for this during episode 3, telling Ryota what happened on the plane ride to the island. He tells Ryota about how he was the most adamant against the game, causing the guards on the plane to taser him right in the head, which explains the blood on his head as well as his short term memory loss back in episode 1.
Ms. Fanservice: Himiko, most of her panel time consists of some action (usually bad for her) that will force a suggestive pose on the girl; while grovelling in pain or fainting, Himiko will have her bosoms, legs or bottom in great view for the reader. Then Junya stepped into the next level, by making an Artbook with a bikini-clad Himiko doing all sorts of poses for a fictional photo shot. She even got a bomb bounced off her chest. And look at some of the merch...
My God, What Have I Done?: Ryota has this reaction at the end of episode 4, after throwing a bomb at Kira and seeing the aftermath of it.
Also his mom tries to slit her wrists because she sent him to the BTOOOM game.
Taira has one of these moments after he realizes Ryouta was still on his side and wanted to escape together, despite having attacked and injured him moments earlier.
My Greatest Failure: Ryouta begins to realize how selfish he was to other people after Taira goes insane and attempts to kill them, and then kills himself when he regains his sanity. He sees that Taira was just a normal person pushed to extreme circumstances, and his failure to stay with him ultimately caused his friend to attack them, then kill himself.
Please Don't Leave Me: Taira begs Ryota not to leave him when the latter goes off to look for a kidnapped Himiko in episode 7. Ryota didn't like it, but he had little choice. If nothing else, to look for some first aid to help Taira.
Plot Coupon: Each player's goal is to collect 7 chips from other players to get off the island. Which makes working with other people more difficult, since you still need eight chips per person to escape, so two people working together would need 14 chips total to escape. Ryota thinks about this during episode 3 when deciding whether working with Taira was going to be worth it.
Pragmatic Adaptation: Himiko's name and backstory are revealed in the second episode of the anime adaptation. In the manga, this happened much later, after Masashi was eliminated, and thus she was a much more mysterious character for most of the plot. This was probably done in the anime to keep the interest of viewers who were wondering who the cute blonde in all the ads was.
Rape as Drama: Himiko's reason for being sent to the island. She and some friends met with an upperclassman. Turns out they were a bunch of rapists. Himiko barely escapes them. Unfortunately, the same couldn't be said for her friends. They blamed her for running away and nominated her for the game.
Rescue Romance: Although it takes a while to happen, Himiko begins to fall into this trope after Ryota rescues her time and again, even though he's risking his life in the process.
Sensor Character: Every player is one, thanks to a "Chip" - a sensor/ transmitter/ radar combo being built into their hand. Not everyone can use it properly though.
Sinister Surveillance: The Tyrannos Corporation uses the Chips in everyone's hands to monitor everything going on on the island.
Taking You with Me: Himiko tries this by activating one of her bombs before getting raped by the big fat guy in episode 2, but he runs away instead. When she realizes she'd only be killing herself, she throws the bomb away, which conveniently lands in front of the guy and blows him up.
Miyamoto attempts to do this as well in episode 7, after suffering from a gas bomb attack. Fortunately Ryota grabbed a bomb off Natsume, whom he just killed moments earlier, and dropped that down to distract Miyamoto long enough for him to let go of Himiko.
Technical Pacifist: Ryota doesn't want to kill anyone unless they give him absolutely no other choice.
They Died Because of You: Ryouta applies this trope to himself when he realizes Taira's death was largely because he seemingly ignored other people's thoughts and feelings, as well as doing whatever he wanted to do. As a result, his friend started going insane due to his injuries, which ultimately led him to attack both Ryouta and Himiko when he starts to hallucinate about his family and meeting them again.
