Kotaro Tatsumi/Relationships

Sakura Minamoto (Zombie #1)
"I have what it takes! Whether or not you have what it takes is irrelevant because I DO! And I’m telling you this, I will never and I mean NEVER abandon you!"

He often intimidates her in morning gatherings but also tends to be friendlier with her than other girls, as pointed out by Yugiri in the eleventh episode. Though, whenever this is brought up, he always either dodges or dismisses their statement.

Albeit Kotaro’s unwillingness to admit that he cares deeply for Sakura, it has been shown throughout the series, as described by Yugiri, on how he is “especially kind to her (Sakura)” compared to the rest of Franchouchou. As evident from how he often consults Sakura’s opinions on his plans for the day before consulting the rest of Franchouchou.

In the first episode, he saves her from the police officer by knocking him unconscious with his shovel. Later on, he gives her a quick pep talk on how he is going to make her an idol, but not before bringing her face closely to his, which visibly makes her blush. He later encourages her to do her best in her first ever performance with the girls, she is visibly inspired by this but simply responds that she could not do it.

In the third episode, he compliments Sakura on her rapping skills despite the performance being done by (mainly) both her and Saki, he quickly covers this up by yelling at Sakura saying how she should not get carried away.

In the fifth episode, he purposefully does the Drive-In Tori dance incorrectly so Sakura could correct him with him playfully going along, to cover this up, he starts yelling at Sakura saying how it does not matter if he does the dance moves wrong.

In the seventh episode, he tells the girls that he wants to have a good look at all of them before they go on with their performance, his gaze lingering on Sakura, whose face (alongside the other girls) is then sprayed with shoe spray in order to preserve their make-up in the rain.

In the tenth episode, he overhears Franchouchou talking about how Sakura’s moving too fast during their choreography making the rest of girls think she should take a break, this prompted him to take them mountain climbing for a training montage telling them he would go back and fetch them once they have learned what they were supposed to do there. After they have all gone back home to the mansion, Yugiri pays Kotaro a visit in a local cafe terrace, exclaiming how she has observed that he is especially kind to Sakura and that she personally has a soft spot for people who can’t outright express their feelings, as he was not willing to admit that he’s doing this all for Sakura and instead hiding it behind the reasoning that he is only doing this to save Saga’s declining popularity. After Sakura snaps and later on realizes that she was on the wrong, she quickly apologizes to her team with Kotaro leaning by the doorframe telling her how it took her long enough to realize that he only bought them up there so that Sakura could come to her senses. Yugiri approaches Kotaro one last time to tell him how she is glad that his plan worked out, but yet again, Kotaro covers this up by pretending to not know what she is talking about.

After getting hit by another truck and regaining her memories, Sakura spirals into a depressive state. After Franchouchou’s many attempts to try and cheer Sakura up and bring her back, Kotaro finally has enough and decides to talk to her himself. He later finds Sakura sulking by a swingset, being confronted by the same policeman from before, and launches Romero at the policeman, effectively knocking him out. Since she does not have any memories of when she was a zombie, she asks him who he is and he gets a bit irritated before telling her that he is Kotaro Tatsumi. He later brings her over a cliff with the view of the prefecture, and has a one-on-one talk with her about how she should not give up so easily despite her terrible luck. And that he does not care if she thinks she does not have what it takes, as long as he himself has what it takes, he makes it clear that he would never abandon her and would help her get through her troubles whether she likes it or not. In the end, he tells her to "respond to her feelings”, which encourages her to get back into Franchouchou and do her best.

In the twelfth episode, it is confirmed that they were classmates in high school, but the nature of this relationship is currently unknown.

Because of Sakura's death, he decides to take up lessons on necromancy and resurrection in order to bring Sakura back so she could live out her dream. Sakura's dream is also the alternate reason why he decided to start up The Zombieland Saga project.

Saki Nikaido (Zombie #2)
"You can’t get near violence, it’s a taboo for idols. Just one of you slips up, and it could ruin everything. Don’t forget that."

In the fourth episode, annoys the girls so much that Saki decides to put him in his place with a blow, In the fifth episode when he hit Saki with a baseball on the head, she threw it back, the ball sank into his right thigh with a force that seemed to penetrate.

They were both excited about going to the Drive-in Tori and the Gatalympics, so much that they started screaming with excitement. Still, he tries to keep Saki from getting into trouble with other gangs and for her fortune she heard his words about not using violence.

Ai Mizuno (Zombie #3)
Before getting motivated, was suspicious of Kotaro's plan, so much that she tried to escape from the mansion but the police made her return.

After Saga Rock, she managed to reconcile with the group and get along better with Kotaro and his crazy plan, even so, she maintains his seriousness with him.

Junko Konno (Zombie #4)
"Get up, Junko! You’re not the kind of girl who would be stopped by something so small."

Like Ai, she distrusted Kotaro's plan to go back to being an idol, not because it was very crazy, but because of how things have changed, this was seen in episode 6 of the series, where Junko says that she cannot be an idol because of how their world has changed in the years she has been dead, locking herself in the attic of the mansion.

Kotaro, as a crazy producer that he is, is going to talk to her in his own way but when he sees that he has knocked her out, he decides to change his way of being and speak in a serious way, which by the way, is the first time in the series in which he does not use violence physical and verbal to talk to the girls.

Yugiri (Zombie #5)
Unlike the other girls, he never bothers Yugiri at the request of the Bartender, in episode 10 they speak directly throughout the series with a serious and calm tone.

Lily Hoshikawa (Zombie #6)
"So you’ve got room for Lily in your little girly club but Masao’s not welcome?!; Right! She’s NOT Masao, she’s Lily. YOU GUYS are Masao, I’M Lily!"

Like the quiet Junko, who often approaches her and intimidates her, he knew Lily's secret but seems not to care because after all "Lily is Lily"

Lily always cooperated with the zombie land Saga plan seeing that in her new life she would never grow old and would always be the girl she wanted to be.

Tae Yamada (Zombie #0)
"The Legendary TAE YAMADA!"

Unfortunately, there is no noticeable interaction with her at the moment why is she number 0? Will such a mystery ever be revealed?

Romero
"Morning, Romero. Good job rangling the girls as always!"

Kotaro's pet dog, he helped him bring the girls to the meetings when they were not awake and also dressed them, as a reward he gave him dried squid.

Mysterious Man (manga only)
After meeting the mysterious man in Drive-in Tori they become good companions, but apparently he has hidden intentions, both visit Saga restaurants frequently.

Bartender
It is shown in the eleventh episode that they are acquaintances, and that it seems that he knows more than Kotaro himself, it is mentioned that like Kotaro he has a past with Yugiri that he still cannot forget. It is noted that it is "Jofuku".
