Kin'emon

"Foxfire Kin'emon" is a samurai from Wano Country, a retainer of the Kozuki Family, the leader of the Nine Red Scabbards, the husband of Tsuru, and a former thug. He posed as Momonosuke's father during the journey to Zou. He was born 56 years before the present day, but traveled 20 years forward in time when he was 36 years old. He is one of the central allies of the Straw Hat Pirates during the Dressrosa and Yonko Sagas. Kin'emon's appearance matches the stereotype of samurai found in ancient Japan, with a black topknot and goatee. At 295 cm (9'8"), he is taller than Brook who stands at 277 cm (9'1"). He is also quite muscular. His eyes are asymmetrical, with his right eye opening more than his left. His attire consists of a samurai gi that is black and white striped on the left side and orange on the right. Kept on the left side of his torso is a pair of katana with identical flame-patterned sheaths. For footwear, he wears simple geta sandals. He has the crest of the Kozuki Family tattooed to his back.

Over 25 years ago, he had light-colored hair and did not wear it in a top-knot. Kin'emon seems to follow the code of bushido, claiming he would commit suicide if he could, for the disgrace of being dismembered without dying. He still tried to maintain his pride, even after being completely dismembered. Like Momonosuke, Kin'emon is very stubborn, constantly refusing the help of others and claiming he does not need it. Only after nearly freezing to death did he finally forsake his pride and ask for help. He is also greatly honorable, as shown when he bowed before Sanji (in Nami's body) for saving his torso and thanked him for helping him, stating he was indebted to him.

Kin'emon has extreme amount of superhuman strength as he can easily cut through a thick steel door and break handcuff chains. With his Haki-imbued swords, Kin'emon could slow down the contraction speed of Doflamingo's Birdcage. He also possesses an immense endurance to pain and cold. His head alone was capable of withstanding Sanji's powerful kicks, and his torso can withstand extremely cold temperatures that a normal person would typically die from and even withstand being viciously bitten by a Shark. He could survive and withstand the Mountain God's violent thrashing, which had enough force to destroy buildings. He was also able to survive being petrified by Caesar's gas, whereas others were presumed finished. Even at the age of fifteen, he was stated to be stronger than the subordinates of the Hyogoro Family, the most prominent Yakuza syndicate of the Flower Capital. In a fit of rage, Kin'emon was able to injure the Mountain God with his katana, causing it to bleed. Noted by Orochi for his tactical intellect, Kin'emon is an extremely clever tactician, having been the one to formulate most of the strategies behind the alliance against the Yonko Kaido.  While in Dressrossa, Kin'emon came up with an idea of disguising Zoro, Luffy, and himself as toys with animal costumes to get away from the Marines without drawing attention and also disguising himself as Doflamingo while searching for Kanjuro in the the royal castle, allowing him to trick Gladius without the latter noticing him as an intruder. In a plan to recruit Shutenmaru, he successfully framed him for stealing supplies from the Beasts Pirates in order to provoke conflict between them.

After being dismembered, his legs were found by Luffy, Zoro, Usopp, and Robin. During this time, his legs seemed to possess the ability to speak autonomously, but after his legs are reattached to his head, it is revealed that he can speak from his legs by using his farts, which disgusted Usopp upon the revelation. As the leader of the Nine Red Scabbards of Kozuki Oden, Kin'emon is one of the most powerful samurai of Wano, noted by Orochi himself to be an incredibly strong master in swordsmanship. His skills are extremely versatile, able to wield either one or dual wield both his swords with incredible power and precision. Even after being dismembered, Kin'emon was capable of putting up a fight with his legs, recklessly attacking Luffy's party when they encountered him. His torso alone was able to match Brook in swordsmanship, utilizing a two-sword style. Alongside Zoro and Brook, Kin'emon was able to cut down multiple G-5 Marines with great ease. During his youth, Kin'emon's skills were acknowledged by Hyogoro, who stated that his subordinates would never stand a chance against him. He was shown being able to fight on par with Ashura Doji when they sparred during their youth. Kin'emon specializes in a sword style he calls Kitsunebi-ryu (狐火流 Kitsunebi-ryū?, literally "Fox-Fire Style"). He is somehow capable of generating, attacking with, and cutting fire with one of his swords. He was able to use this technique to clear the way off the Slime and even cut through the subsequent explosion caused by its detonation after being ignited. His fire enhanced sword slashes are powerful enough to seriously injure a dragon, despite its scales being stronger than steel. Kin'emon ate the Fuku Fuku no Mi, a Paramecia-type Devil Fruit that allows him to transform objects placed on a person's heads into various kinds of clothing, which disappear once removed. Furthermore he must first visualize the appearance of the clothes, otherwise his creations would be limited. However, he was not aware that what he ate was a Devil Fruit, but he does know about the weaknesses involved with it. Kin'emon has shown the ability to use Kenbunshoku Haki, as even after being dismembered by Law, his legs and his torso were able to fight, and even defeat people without being attached to his head. When Kin'emon's disembodied legs first "spoke", it said it could feel the "aura" of other people and accurately attacked his opponents. Furthermore, his separated body parts navigated by 'sensing' their surroundings (though his legs still managed to somehow get stuck to a dragon). Kin'emon displayed the ability to use Busoshoku Haki, known in Wano as "Ryuo", when he hardened his sword to slow down Doflamingo's Birdcage. His Busoshoku Haki is strong enough to withstand the Birdcage's razor sharp threads that can slice cannon balls with ease.

Apple and Google are building a Covid-19 tracking system into iOS and Android

Apple and Google announced a system for tracking the spread of the new coronavirus, allowing users to share data through Bluetooth Low Energy (BLE) transmissions and approved apps from health organizations. The new system, which is laid out in a series of documents and white papers, would use short-range Bluetooth communications to establish a voluntary contact-tracing network, keeping extensive data on phones that have been in close proximity with each other. Official apps from public health authorities will get access to this data, and users who download them can report if they’ve been diagnosed with COVID-19.

The system will also alert people who download them to whether they were in close contact with an infected person. Apple and Google will introduce a pair of iOS and Android APIs in mid-May and make sure these health authorities’ apps can implement them. During this phase, users will still have to download an app to participate in contact-tracing, which could limit adoption. But in the months after the API is complete, the companies will work on building tracing functionality into the underlying operating system, as an option immediately available to everyone with an iOS or Android phone. Contact tracing which involves figuring out who an infected person has been in contact with and trying to prevent them from infecting others is one of the most promising solutions for containing COVID-19, but using digital surveillance technology to do it raises massive privacy concerns and questions about effectiveness. Earlier this week, the American Civil Liberties Union raised concerns about tracking users with phone data, arguing that any system would need to be limited in scope and avoid compromising user privacy.

Unlike some other methods like, say, using GPS data this Bluetooth plan wouldn’t track people’s physical location. It would basically pick up the signals of nearby phones at 5-minute intervals and store the connections between them in a database. If one person tests positive for the novel coronavirus, they could tell the app they’ve been infected, and it could notify other people whose phones passed within close range in the preceding days. The system also takes a number of steps to prevent people from being identified, even after they’ve shared their data. While the app regularly sends information out over Bluetooth, it broadcasts an anonymous key rather than a static identity, and those keys cycle every 15 minutes to preserve privacy. Even once a person shares that they’ve been infected, the app will only share keys from the specific period in which they were contagious. Crucially, there is no centrally accessible master list of which phones have matched, contagious or otherwise. That’s because the phones themselves are performing the cryptographic calculations required to protect privacy. The central servers only maintain the database of shared keys, rather than the interactions between those keys. The method still has potential weaknesses. In crowded areas, it could flag people in adjacent rooms who aren’t actually sharing space with the user, making people worry unnecessarily. It may also not capture the nuance of how long someone was exposed working next to an infected person all day, for example, will expose you to a much greater viral load than walking by them on the street. And it depends on people having apps in the short term and up-to-date smartphones in the long term, which could mean it’s less effective in areas with lower connectivity. It’s also a relatively new program, and Apple and Google are still talking to public health authorities and other stakeholders about how to run it. This system probably can’t replace old-fashioned methods of contact tracing which involve interviewing infected people about where they’ve been and who they’ve spent time with but it could offer a high-tech supplement using a device that billions of people already own.
