By the time he finds her on a ship, Chihiro confesses she started liking Keima since they're both similar of being disappointed with the real world. However, he corrects her that despite his dislike with the real world, he never given up on himself so she should she do the same thing. But when Chihiro tries protest that someone as average as her can never be special, Keima kisses her by surprise and tells her as long as she truly wants it, nothing can stop her from becoming special, which forces the spirit out.

Jun Nagase is an idealistic and upbeat new student teacher at Majima Academy assigned to her senior's class, Miss Nikaidō, Keima's teacher. Jun is at first bewildered that Keima is playing video games in class and nobody minds about it but after the teachers tell her the problems they have to deal with him, Jun believes Keima is a problem child and wants to help him. She goes to talk to him but gets scared looking into his eyes and leaves. Convinced that Keima is actually lonely, she resolves to help him open up which at the same time a spirit enters her body. When Keima and Elsie learns about Jun's spirit, Keima finds his next target difficult as making of a teacher falling in love in games takes too much time as teachers never fall in love with their students as they only see them as their students only. Thus in order to make Jun fall in love with him, he has to make Jun see him as her equal in a short amount of time. As Keima leaves school to figure out his plan, he is caught by Jun who thinks he's ditching school. After dragging him to have lunch with her and talking about her idol, the late pro wrestler Jumbo Tsuruma, Jun tell Keima to talk about his problems to her. However Keima does not like this unprecedent event since it will take too long for him to capture Jun's heart.

Keima has an idea to quickly grow the relationship between him and Jun by making her hate him and turning those feelings into love. But the plan backfires as it only cause Jun to be more concerned about him. After getting him alone in class, Jun tell Keima that she believes he is lonely and plays games as a form of escape but he shoots her down as she has no clue what he is and that she shouldn't judge him by her own standards, which leaves Jun shocked. With no other choice and a change of plans, Keima asks Miss Nikaidō for more information about Jun which she agree in exchange for helping her in her school work. Meanwhile, Jun still affected by Keima words, decides to help his class in their schoolwork after Mr Kodama insult them as failures. But when the students tell her that they don't have the zeal to improve themselves, Jun in anger, inadvertently scolds them and quickly leaves. After finishing his part of the deal, Nikaidō finally reveals to Keima that she and Jun were members of the highschool's girls basketball team before it disbanded over an incident in the past. With this new information, Keima now knows what to do.

Still upset over what happened at class, Jun goes to watch a pro wrestling match only to find Keima sitting at her seat thanks to Elsie making a copy of her ticket. As she is forced to sit with him to watch the match, Jun wonders why the class won't let her help them, which Keima then asks her why the girls basketball team disbanded when she was captain and correctly concludes that it was her idealism that forced the other members to quit and despite claiming she was trying to help the team for them, she was actually helping them for herself which Jun leaves the match in anger. Despite this, Keima concludes it's time to capture her heart. Later, Jun tells the class she has entered them for a marathon hoping to help them bond, but instead they refuse, feeling that she's trying too hard on them, which leaves Jun disappointed and tells the class how selfish they are before running away. As the class bad mouths Jun, Keima unexpectedly calls out on their behavior and disappearing before they confront him. As Jun arrives at the old girls basketball team locker room, Keima confronts her, telling her despite claiming to have changed in order to teach her idealism to others, she still hasn't changed at all. As she runs away into the school gym crying and wondering why people won't let them help her, Keima consoles and tells her to not give up and try harder as it will finally make them accept her idealism. Just then, the whole class arrive in the gym to apologize to Jun much to her joy. Unknown to Jun, Keima knew what was going to happen so he planned with Elsie to have the class to start hating him after Jun left and made them worry about her after she was gone. As Jun's time as a student teacher comes to an end, Keima sees her off and asks her to come back which she promises to become a better teacher and kisses him, finally expelling the spirit inside of her.

While playing his recently bought dating sim games, Keima plays one called "One Leaf". At first, he assumes it's a terrible game due to it's horrible character design but quickly falls in love with it's heroine, Yotsuba Sugimoto, aka "Yokkyun", as she is his ideal game heroine. Keima enjoys the game so much, that he decides to play it at a slow pace, ignoring everyone throughout the whole day much to Elsie's chargin and Haqua's confusion. Later that night, Keima receives an email from the game studio that created "One Leaf", who asks Keima to help them create the perfect dating sim game under his direction. As Keima think of ideas for the game, his inner minds soon starts arguing over what is the ideal and perfect dating sim which leads to an intergalatic war. But the war finally stops when all of them remember about Yokkyun and what is important that makes the perfect dating sim game. Finally making a decision, Keima decides to tell the studio to just make a good game. As the season finale come to an end, including a preview of the new cast of heroines for Keima in the next season, Keima ends the episode saying he used to think games were the ideal world and real life was just a bad game.

Keima explains to the audience how he has captured fourteen girls and two unique girls after the last season. Meanwhile, Kanon is preparing for her school tests, but ends up talking with her split personality, Apollo, who claims to be a goddess. The next day, Keima and Elsie meet up with Tenri and within her, Diana. Diana wants Keima to marry Tenri as Tenri's love for Keima increases her powers, which he refuses. When asked to explain what she is, Diana reveals she is a goddess, one of the Jupiter Sisters, who helped the New Demons of Hell against the Weiss, when they attempted to take over the three realms of Earth, Heaven and Hell, and control all souls. After defeating them, the Jupiter Sisters sacrificed themselves by sealing themselves together with the Weiss, but they escaped ten years ago. Diana asks Keima to help find her sisters and reveals they reside in his past conquests, who did not forget their memories with him.

Apollo casts a warning in the sky to her sisters to trust no one before succumbing to her wounds. Lune attempts to finish her but is stopped by Nikaidō. Keima, Diana, Elsie and Haqua have Apollo taken to the Katsuragi household where they discover the magic dagger used on Apollo and Kanon is ancient Weiss magic and the culprits are Vintage, a group of demons who wish to resurrect the Weiss. With Kanon having a week to live, Keima must find the other four goddesses to heal her before Vintage gets them. To accomplish this without incident, Elsie disguises herself as Kanon and Keima tricks his mother to go to South America. Partnering with Haqua who is disguised as Elsie, Keima uses the rumor of Kanon's confession to see the reactions of his prior conquests, who will act jealous if they remember falling in love with him. Keima narrows his suspects to Ayumi, Chihiro, Shiori and Tsukiyo Kujyo, who were all embarrassed around him.

Keima plans to spend an hour each with the girls to raise their affection for him without any of them encountering each other with Haqua's help. He manages to succeed with Tsukiyo on the bus but compilations occur when the 2B-Pencils finish band practice early which leaves Haqua with Chihiro. As a result, he misses Yui but continues by walking home with Ayumi and Miyako. Unfortunately, Haqua and Chihiro are heading in the same direction which prompts him to take Ayumi and Miyako inside the mall. After making sure Chihiro is busy with Haqua, he has a private talk with Ayumi that he won't give up on her. Next, he meets up with Chihiro at the music store where he praises a song she wrote. Later, he heads towards the library to meet with Shiori where he finds a story written about them that resembles her conquest with the roles reversed but his character is killed due to the rumors with Kanon.

Keima arrives at the library whereupon Shiori allows him to read her story while being watched. Meanwhile, Nora discovers Kanon and demands Haqua an explanation. In the library Keima discovers that Luna, Tsukiyo's doll, is Vulcanus who warns Keima never to approach Tsukiyo again. Attempting to stop Vulcanus from being discovered, he approaches Tsukiyo not realizing she is in fact truly Vulcanus controlling objects. With both Vulcanus and Tsukiyo mad at Keima for cheating on her, he makes Tsukiyo remember the promise he made to her. Succumbing to her pity for his injury, Tsukiyo kisses Keima whereupon she grows wings. Nora explains to Haqua that Vintage have infiltrated the spirit hunters and the search order for the goddesses is a plot to capture them. Reunited, Diana and Vulcanus combined their powers to removes the cursed dagger but Apollo turns Kanon's body into a liquid state as a preservation measure.

Keima sends Tsukiyo home warning Vulcanus not to reveal herself while he searches for the other goddesses. Unexpectedly, Yui has come to Keima's home to ask him out. Keima explains to Haqua he must now conquer Yui before Vintage realizes she has a goddess. The next day, Keima crossdress as a girl which gains Yui interest to awaken her past memories while unknowingly being overseen by Shiori. After Keima asks her out for a date, the goddess Mars finally awakens inside of Yui. As the crossdressing couple spend time together on their date at an amusement park, Keima is kidnapped by a Vintage agent. Wishing to save Keima, Yui's love for him finally restores Mars' powers which she defeats the agent who is revealed to be Haqua which was a part of Keima's plan to awaken her powers. Yui proclaims her love for Keima and kisses him, which restore Mars' wings.

After several drafts and procrastination by reading books, Keima eventually tells Shiori to write about herself especially when they both lock themselves in the library. Realizing Keima was there and kissed her during that time, Shiori starts writing. The next morning, Keima reads her story about her life at the library which ends with her declaring she loves Keima.
