Ways to kill the one
by Namelesspassenger
The walk from Bar Lupin to the apartment was a long one. Although he only lived fifteen minutes away from there, those fifteen minutes felt like hours for Sakunosuke Oda and the (former) port mafia boss Osamu Dazai. Neither of them said anything – they both knew it wasn’t needed. A few whiskey s

by mochhka
School is quite a dreadful thing, a universal fear. Students and teachers alike despise it, from the hallways to the lights—and especially that stuck up prick of a prodigy: Fyodor Dostoyevsky Dazai’s favorite little enigma.
