* CompleteMonster: Hasegawa is the despotic leader of the Red Imperial Army and an EvilutionaryBiologist who intends to create the "perfect" specimen of soldiers to enforce his dictatorship. [[EstablishingCharacterMoment Introduced]] having hundreds of test subjects which he deemed a "failure" disposed of by personally dropping them, one at a time, down a chute leading into a grinder where they get grounded into a bloody pulp, Hasegawa orders his minions to have the immortal Kuro captured while leaving no witnesses, resulting in innumerable civilian casualties which he doesn't bat an eye towards. Launching raid after raid resulting in the deaths of Kuro's allies, including resistance leader Saniwa and Kuro's friend Kuon, Hasegawa had Kuro and the remaining resistance members LuredIntoATrap when they tried infiltrating his headquarters. After capturing Kuro, Hasegawa threatens to use Kuro's LoveInterest Rai as a test subject, before finally injecting himself with a SuperSerum, turning himself into a literal monster to brutally asssault Kuro.
