The BS was quickly out of the prison with his real clothes but not his bike.. No-One knows where the bike is but there were so many rumors about the bike. The world you might be thinking that BS lives in right now is probably with humans, natural disasters, political problems, pollution and more but you are wrong. The World BS is living in has Demons, Heroes, Aliens , villains and many many more dangerous mystical creatures that want to take over earth or destroy everything in it. The Heroes put BS in jail because he was neither a hero or villains and you have to chose if you go against humanity or support it. So maybe it does have some political problems. Anyway He fought back for 2 years then got bored of running and gave up. Then after 15 years he has escaped because he doesn't want to work for random people. In a world with heroes and beasts you might be thinking why would they leave a beastly Samurai guarded by some humans, That is because of the woods that they are surrounded by. The Forest is not made for any human so the government didn't want to waste troops. They only use planes for any kind of transportation. The Forest is dangerous but creatures don't attack a "gang" of some sort of creature. Since there were 40 to 50 humans protecting the Prisoners and themselves they weren't in danger.
