Durarara!! RE;Dollars Arc Series by Aogiri, Ryohgo Narita, Chiho Christie, Suzuhito Yasuda

Mikado Ryuugamine is just trying to pass his second year of high school peacefully, but when he gets word that someone within the Dollars gang is causing trouble, that's out the window. Everybody's in trouble: Izaya is scheming, Mikado's classmate knows his secret, and Shizuo's being targeted by a mysterious girl--just another day in Ikebukuro!

Tension in Ikebukuro is at an all-time high with Toramaru in town seeking revenge on the Dollars, but that isn't the only problem... With the Dollars' members acting out, Shizuo on the run, and Izaya dragging the Yakuza into the mix, will Mikado ever be able to keep things under control and go back to his everyday life?!

In his younger days, yakuza officer Akabayashi met Sayaka, the mother of Anri Sonohara, who held Saika within her...and this chance encounter changed his life forever. Meanwhile, Mikado begins a purge of the violent members of Dollars, an assassin menaces Izaya, and somehow Shizuo's getting all the ladies...?! There's never time to sit back and relax in Ikebukuro!

Shizuo gets caught up in a violent fight between a foreigner and a mysterious zombie-masked adversary, and he sends them both flying! Coincidentally, Shizuo's brother, Kasuka, witnesses the zombie's crash landing and takes off its mask to reveal the identity of Hollywood. Hollywood is the suspect in a string of recent murders in the city...so why does star idol Ruri Hijiribe keep popping up around the incidents?! It seems Ikebukuro's as action packed as ever!

Megahit idol Ruri Hijiribe is suffering at the hands of a stalker, and his obsession with her is growing by the day. In order to see how she reacts, he becomes more strident in attacking and hurting those around her. One of the innocent (?) victims is the doctor and love of Celty the Headless Rider, Shinra Kishitani. As she clutches his wounded body, Celty loses her head with rage! (Literally.) And you just know who else is gonna show up behind the scenes...It's Ikebukuro, after all!

As a founding member of the Dollars color gang, Mikado Ryuugamine methodically purges those unharmonious from its ranks. Kida attempts to rein in his friend's madness and begs Kadota's group of core Dollars members to leave, but they refuse. However, when calamity befalls Kadota, the spark of a new disaster catches flame...Meanwhile, in the hospital, Shinra tells Celty of his middle school days with Izaya Orihara...!

Dotachin was the victim of a hit-and-run. So say the latest rumors running rampant through the town of Ikebukuro. And when rumors take on life of their own, chaos and confusion rule the roost! Those suspected of the crime, those who avenge crime, those who exploit crime-ambition and desire spiral out of control while the mystery of the Dotachin incident has yet to be resolved!!

Dotachin has been hospitalized after a hit-and-run, but Izaya insists he had nothing to do with it, or with Ryuugamine and Kida. Meanwhile, Celty's head has been left in Ikebukuro and winds up on live TV!
