Later Paka takes them inside the tower where he meets the other gamers that were chosen for the game. Paka wanted everyone to introduce themselves starting with Iride. When it was his turn he introduced himself like nothing was going on. After that, Paka informs them about the second stage which is called Oujia Board Exchange where everyone has to pull a straw and whoever gets one must participate in the second stage. He doesn't get a Paka straw which means he won't participate in the second stage.

Episode 2 (Stage 3)
Kaikoku was summoned with the others outside so that Paka can explain to them the second stage. Whilst everyone seems quite miserable about having to go along with this, Yuzu and Aki are excited once they see the giant egg. The next stage is revealed by Paka to be a nurturing game where they must hatch a girl from the egg and make the school idol Hikaru Genju fall in love with her and he says how there is no limit to how many people can take part but it must be a minimum of four. Anya looks to Himiko saying how she's the obvious choice to put on the team. She then hides behind Aki. Kaikoku was asked if he will participate but he refused and instead said that he'll go to explore. Zakuro has noticed Kaikoku heading where Paka has gone and decided to follow both of them.

Episode 3 (Stage 4)
Kaikoku and the others were in the lobby when Kaikoku showed up with Zakuro. Kaikoku told them that when they were busy with the 3rd stage, he and Zakuro have intruded floor 51 which was prohibited for all of them. While they were reporting what has happened, they were attacked by a Plant Monster. It caught Zakuro's leg. Paka then opened the speaker and said that since they have broken into floor 51, stage 4 will become an S-level stage, called "Exterminate the Mimicry Man-Eaters". Kaikoku then saves Zakuro but was going to hit Anya as well, they started arguing when Himiko threw a flashbang onto the monster causing it to fall down and separating the group. Iride and Anya were separated from the rest, Yuzu tells them to meet them in the food storage in the basement. At the basement, Anya was sleeping due to not having enough rest as stated by Yuzu. Iride explains to everyone what they have encountered which was a Mimicry Man-Eater disguised as Karin. It pisses off Karin knowing that it got close to Iride. Yuzu then says to Kaikoku to accompany her to her room as her bodyguard and gives a task to Iride and Zakuro to bring the withered Mimicry Man-Eater to her. At Yuzu's room, she has found what she wanted, a bag containing poison. Kaikoku asks where she got them and she replied with it's her hobby. She stood up and a photo falls from her, Kaikoku picks the photo and tells her you dropped it, but when he saw forward he was shocked with what he saw. He saw Yuzu's closet full of pictures about Iride and she tells him to keep it a secret from Iride.

After Yuzu has made her investigation on the Mimicry Man-Eater, she tells everyone that at sunset all of them are going to eradicate the Mimicry Man-Eaters. She displays her box of poison she has brought from her room explaining to everyone that it will be divided by all of them. Zakuro asks Yuzu from where did she get all this poison. She affirms that she keeps it as self-defense against bullying and perverts, she adds to it that Himiko is doing the same thing as well. Suddenly the speaker started revealing Paka's voice, he tells them it's been a week since they have been in this world and they have passed 5 million views, which is first in the game's history. He feels honored as being responsible for the 13th district. After he was done with his announcement, Yuzu starts to begin her operation. She says Iride, Zakuro, Anya, and Kaikoku to inject the poison on the core of the ivy. She tasks Karin to help her, Himiko to cook, and Makino on sleeping duty. Yuzu adds they need a password to know if they aren't fake. The password was whenever someone says Karin the other replies with pudding, leaving Karin confused. The four eating Himiko's pudding and they had 10 seconds for their operation to begin and off they go.

When Iride and Anya caught up with Zakuro and Kaikoku they encounter two copies of Makino unaware who is the real one. Iride tries the password Yuzu has given them but Zakuro says Makino was sleeping when they announced the password. Anya and Zakuro start to argue and suddenly the two Makino imposters attack them, but they survive. When they reach back to the basement everyone goes to sleep.

The next day, everyone wakes up realizing stage 4 has been completed. They see the monsters were withered because of the poison. Karin looks at Yuzu wondering what is she up with Iride since she is hugging him and she's happy that he's safe. Then she adds "I should've kissed him while I had the chance" leaving everyone confused on what she was saying.

He accompanies them to an elder where he will continue the rest of the story and he leaves. Iride heads to the house as he will enter the first but Anya stops him stating he should be cautious. He states it will be fine and it's not like someone with a knife will stab him, he opens the door and a girl rushing towards him wanting to kill him but he was saved by Kaikoku. The girl then asks if they were demons and they weren't so she takes them to the elder so he can explain what is happening. When they enter, the elder introduces himself reveling his name, Kihachi and the girl is his granddaughter Kikka and he was sorry for what she did. He adds that tonight a demon will abduct a girl and he is afraid if it will be his granddaughter.

He realizes that they have come to end the demon situation so he gives them 2 sacrificial robes so they complete the stage. Yuzu states that it's a good thing to locate the demon's base if one of them was abducted, Kaikoku adds that maybe they're dead but Kikka tells them they're not but was silenced by her grandfather. The group starts discussing who will participate, Yuzu says Kaikoku and Zakuro will be the first two and adds if there was any volunteer, Iride volunteers as usual. Kihachi cuts them saying the legend says that the demons love bouncy and busty bodies. Everyone starts to argue on who will wear one of the robes to join Iride and Himiko is trying her best to calm them down but it was no use so she uses her weapon to quiet everyone. When everyone calmed down, Yuzu had an idea which was dressing Makino since he was sleeping all the time.

Outside Zakuro asks Yuzu why did she pick Makino, she stats that anyone will be caught in Makino's eyes whatever their race or age is. Kaikoku tries to look at his eyes but he feels disgusted from it. Himiko realizes Iride and Anya are chatting with each other so she heads to them asking if they did makeup after they fight. Anya says it wasn't really a fight, Iride states that he went to Paka for sleeping drug so he can sleep but when he showed it to him Anya got mad and punched him. Then everyone went hiding in the bushes and waiting for the demon to appear. Kikka appears behind them in silence she says that all of them were stupid, she wanted to kill them especially Kaikoku since he got her earlier. Kaikoku notices Kikka behind him and tells her what is she doing here, she freaks out but she tells him there's a bug on his back. He tells Zakuro to remove it but he gives a commentary about it.

Iride says it will be like a trial and they can kill him if they didn't need him. Anya yells at Iride saying what is he doing this, he states that he can't leave Karin alone, he then leaves with Kihachi, Kikka, and Karin. Anya says that we don't know where they are going to but Yuzu claims that she has put a transmitter on Iride's neck which would be easier to locate them. (end of episode 4)

She yells at Kaikoku and Zakuro about how they are annoying and about their interference to her stuff. She then looks closely to Zakuro and stating that she has seen his face somewhere before. Zakuro gets angry and yells at her about his sister if she has seen her before. Kikka says she couldn't remember but Zakuro refuses it and takes out his knife aiming to kill her. Kikka tells she might have eliminated her causing Zakuro to rage but Kaikoku stopped him saying people who can't control their anger block the path. Zakuro lets Kaikoku handle the rest of the situation. Kaikoku knew Kikka was lying at Zakuro so he instead threatens her. She gets furious and calls her grandfather to come and destroy Kaikoku, but he doesn't come leaving Kikka in depression.
