Walker Yumasaki

Walker Yumasaki (遊馬崎 ウォーカー, Yūmasaki Wōkā), like his female friend and companion, Erika, is a very passionate otaku and manga reader, although he doesn't share the same love for yaoi that Erika does. He and Erika are nearly always together. He also likes to perform torture by letting the victim to choose a light novel or manga, and carrying out the contents. He seems to be carefree and is usually seen wearing a wide dumb smile, but in reality he's a serious thinker. Like Erika he is very mysterious person. He is a member of the anonymous online gang Dollars and is also a member of Kadota's gang. In the later episodes, Walker was asked to remain inside the van for the invasion of the Yellow Scarves, because he would "stand out too much". He can also be seen with Erika in the hospital in the last episode, with her head lying on his shoulder.

After they part ways, Erika and Walker are walking with Kyohei when the spot Mairu and Kururi being harrassed. After Kyohei chases off Toromaru and calls in Togusa to pick them up, the Toromaru members return in force and chase the six of them across the city. They pick up Anri, Mikado, and Aoba along the way as well as join up with Celty who is also being chased.

Volume 05 & 06 : Walker goes into a gift shop to buy a painting but immediately recognizes it as a copy and calls out the manager on selling a fake at such a steep price. the scene also attracts the attention of Chikage who found out about Walker's status as a dollars member from one of the thugs that he had taken hostage. After Walker leaves the store in a huff, Chikage starts tailing him all the way to where he is meeting Kyohei and the others. Kyohei notices Chikage and eventually seperates from his friends. Eventually, after Chikage and Kyohei are cornered by the rogue dollars members, Walker, Erika, and Saburo arrive with reinforcements. When the kidnappers were distracted by Vorona's flashbang, Walker swooped in and chased off the guy who had a knife to Non's throat. with their bonds cut, the girls flocked behind walker who held a makeshift flamethrower (a spray can and a lit match) in his hand that he used to keep the kidnappers at bay. Walker and Erika spent most of the fight protecting the girls until Anri and Vorona entered the fray where Walker and Erika witness Anri and Saika in action. After the fighting has dies down and Anri leaves, Walker and the rest of the Van crew turn to leave. After Erika makes her newest pair (Chikage and Kyohei) apparent to the group, Walker expresses his annoyance at how fujoshis (yaoi fans) seem to pair up just about every male character they see regardless of things like age or how they relate to each other.

Volume 09 : Walker is next seen hanging out with Kyohei and Saburo at Russia sushi, expressing a sense of lonliness without Erika around (since she's the only other person that he can talk to about manga). He also witnesses Masaomi's return to ikebukuro.
