Takano Masamune Edit. Masamune is Ritsu's current boss, neighbor and first love in high school. In the manga, Masamune and Ritsu have been neighbors for quite a while but they never met or even introduced themselves due to irregular times arriving home while Ritsu was still working at his father's company.
It's nearly 50 years since the US landed men on the moon, but Americans are still dying from a disease that ravaged Europe in the Middle Ages. Why hasn't the US eradicated the plague? The Black Death caused about 50 million deaths across Africa, Asia and Europe in the 14th Century. It wiped out up to half of Europe's population. Its last terrifying outbreak in London was the Great Plague of 1665, which killed about a fifth of the city's inhabitants. Then there was a 19th Century pandemic in China and India, which killed more than 12 million.
The Great Plague epidemic of 1665 is believed to have killed a sixth of London's inhabitants, or 80,000 people, and it is sometimes suggested that the fire saved lives in the long run by burning down so much unsanitary housing with their rats and their fleas which transmitted the plague, as plague epidemics did not recur in London after the fire.
