Romero/Relationships

Sakura Minamoto (Zombie #1)
Sakura is shown to be afraid of him at first, after witnessing him morph into his more terrifying form as he happily accepts the dried squid Kotaro rewards him with for doing a good job on rallying the girls together, but the two’s bond have seemingly grown off-screen throughout the series as Sakura was comfortable enough to invite him over to her morning jog in the tenth episode. After she gets hit by another truck, Romero quickly tries scares the truck driver away as to cover up her identity as part of the undead, since at the time, she did not have her make-up on. As the truck driver leaves, he quickly scurries back to Sakura’s side and whimpers and barks loudly, showing his concern.

Saki Nikaido (Zombie #2)
The two have yet to interact on-screen but it appears they are on good terms as he has no problem hanging around her with the rest of the girls, as well as the fact that Saki does not seem to be fazed by him.

Ai Mizuno (Zombie #3)
During Ai's escape attempt in the second episode, she sees Romero sleeping by the exit of the mansion. Upon awakening him, Romero thinks that she is there to play and transforms into the scariest form of her, pounding on the door with enthusiasm, scaring Ai.

In the sixth episode, Ai comments on her group's fan merchandise, designed by Kotaro, that she has a chibi art of Romero sewn into the towels, indicating that it is a "strange design". But due to Ai's likes she wore a keychain in the Chibi shape of Romero to work after the failure of the EFS.

Junko Konno (Zombie #4)
Like Saki, the two have little to no onscreen interactions, but it is safe to say that they are both fine with each other’s presence and are in good terms.

Yugiri (Zombie #5)
In the Meiji era Romero and Yugiri interacted from time to time when Yugiri took care of an old Jofuku giving him his medicine, although it is not seen on the screen it is implied that both knew each other and interacted from time to time, which would explain why Yugiri reacts normally with Romero in the first episodes of the first season. Yugiri also asks Romero to take care of Tae when she goes shopping to avoid discovering the girls since she knows that Romero is a faithful and trustworthy dog.

Lily Hoshikawa (Zombie #6)
They have a similar situation to Saki and Junko, but the two are shown to be in friendly terms, as he was seen resting on Lily’s head during the van ride in the ninth episode.

Tae Yamada (Zombie #0)
Tae is the member of the group he hangs out with the most, considering the fact that the two share similar personalities and habits. Some of her shared activities include howling at the moon at night, sleeping on the front porch of the mansion at times, and growling at suspicious people. During the second season it is evident that Romero goes shopping with Tae from time to time and the two of them get along well with the inhabitants of Saga, Romero defends Tae from being photographed by Ookoba once scaring him and throwing Arata to the floor, when he is It is about Tae's safety and he does everything possible so that he does not make scandals that could cause them to discover that they are zombies.

Kotaro Tatsumi
Kotaro is Romero’s master and the two share a healthy relationship. He tends to follow Kotaro and the girls around, Kotaro gets him to help the girls out at time, such as rounding them up for their morning assemblies, to which Kotaro rewards him with the same dried squid he feeds the girls in the first episode.

Police Officer
Seeing as how the police officer is on the opposing side of Kotaro and the girls, he is not against the idea of doing anything to have to stop him. As he is seen being used as a projectile who is then launched by Kotaro to knock him out in the eleventh episode when the officer tries to approach a sulking Sakura with no make-up on.

Truck Driver (Episode 10)
In order to keep Sakura’s undead identity a secret, he had to scare the old man away from trying to help her. It can be assumed that he also holds some resentment for the driver, considering how he hit her with a truck, albeit accidentally.

Jofuku
Their specific relationship is unknown, during the Meiji era Romero was Jofuku's pet dog and who kept him company when he was alone because at that time Saga had disappeared from the map, also Romero was visibly worried about Jofuku when he almost died at the end from episode 21. Romero/Relaciones
