Ultra despair girls - Hajime Touya

Komaru and Toko delve into the subway tunnels, finding an underground arena where Masaru, leader of the killer kids who call themselves the Warriors of Hope, stands triumphant above a pile of dead grown-ups... yet the boy doesn't stand a chance against Genocide Jill and Komaru's teamwork! Now having defeated a foe, the question arises as to who's actually their friend... Shirokuma, a bleached, bandaged version of their teddy bear tormenter, claims to be able to put them in touch with the adult resistance - but is following it down even deeper really such a good idea?
