Heaven's Memo Pad

Narumi, a high-school freshman, accidentally crosses paths with a group of NEET when a young girl jumps from a hotel window and lands in a trash pile right in front of him.

Alice's new case is another missing person, but this time it's a guy who's having problems with the Yakuza. The case is brought to her by his daughter, Meo, who is worried after receiving a phone call from him that's quite grim. Narumi, the new assistant, is tasked with some investigating, but doesn't find much.

The Yakuza show up for the money that Meo has, but Minli, owner of the ramen shop where Alice sets up HQ, refuses them. The next day, Narumi finds that Meo has disappeared with the money. Despite Alice's warnings, he rushes off to find her. When he finds her, they are attacked by the Yakuza. Narumi is getting beaten up, but then the guys from the dojo show up to dish out some pain. Realizing his weakness, Narumi asks the Fourth, leader of the dojo, to perform a sake ritual with him to formally induct him into the dojo. With that done, there is still the problem of the money Meo has. However, Narumi gets the idea to split the money into small portions and transfer them all into Kusakabe's bank account (Kusakabe is Meo's father), scheduling all of it to be transferred to the corporation that's after Meo, the Kishiwada Corporation.

Minli's sarashi is stolen by a stalker and so the gang decides to go out and find the culprit. Alice attempts to act arrogant when Minli asks for her help, but Minli quickly stops this by picking her up. Minli initially refuses Alice's help, but after some comments from Narumi, she changes her mind. They start by investigating the strange man that has been coming into the ramen shop. He buys a ramen, takes one sip, then pays and leaves. They try to tail him, but lose him. Later, Narumi is telling Alice about a lock that Minli refuses to have changed. Alice realizes something and tells everyone to drop the security around the shop. Major gives Narumi a strange ball and tells him to use it if he sees the intruder. Narumi throws it at the suspicious man and it turns out to be a flashbang. The man turns out to be an executive from a lingerie department.

Alice's annoyed at Narumi for trying to wash her stuffed animals. The Fourth walks in to ask Narumi to help him run a concert. Alice shows off a little tsundere at the thought of Narumi being away and busy with the concert. The Fourth later talks to Narumi alone and tells him that the job is more dangerous than he let on. Turns out one of the band's former promoters is the Yanagihara Group, who have ties with the Yakuza. The band didn't want that group to sponsor them, so they turned to the Fourth. However, it's possible that the Yanagihara Group bites back. Narumi starts to promote and help out with the concert. While he's out alone, he runs into a man named Hirasaka, who is being threatened by some thugs. He starts to beat the crap out of them, but Narumi stops him by pouring his drink on Hirasaka's shirt.

Narumi ran into Renji at the zoo. The two have a nice chat about random things and Renji mentions a friend that he used to have in Tokyo. Narumi gets called to go back to work at the concert again, but Renji tries to stop him for some reason. He returns to see the fire trucks, as the venue has been set on fire. Also, Alice shows up, having worried about Narumi because he didn't pick up his phone and his GPS was by the fire. The Fourth also calls Narumi to ask him about the fire as well as tell him that they have found the one who stole their t-shirts in the last episode. Narumi shows up to see the culprit, and the culprit starts saying random things about angels and mentions Hirasaka. The Fourth then beats the crap out of him, but later tells Narumi that there was another person that had the key to the room with the t-shirts.

Narumi meet Renji to talk. Renji tells Narumi that he will kill him if he sees him again, but Narumi tries to convince Renji to tell him the story between the Fourth and him. Renji starts to tell him, revealing that the Fourth and him lived together with a girl named Hison before. The two men had an agreement that neither would make a move on Hison and that both would protect her from other men. Renji tells Narumi that the Fourth used Hison as a shield in a fight against the Gotouda Group, causing her death. Renji vows revenge and tells Narumi to stay out of it. Narumi later talks with Yoshiki, who tells him a bit about the Fourth. Narumi realizes how much the Fourth cared about Renji and calls him to beg him to ask Alice for help. The Fourth later comes by the ramen shop to finally ask Alice to help him out, and he finds out that the other NEETs were already on it. Narumi confronts the Fourth about Hison, but the Fourth refuses to tell him more.

Narumi rushes to the hospital in response to his call telling him that the Fourth was attacked. He is in unstable condition and unconscious, which Narumi relays to Alice. Maki calls from the concert to ask Narumi to email her the concert documents. However, when Narumi goes to do it, he finds an email from the Fourth addressed to him, half done and telling him that he's in charge if something were to happen to the Fourth. Narumi goes back to the ramen shop to find the rest of the guys ready to go out and kill Renji, but he is able to stop them from dirtying the Fourth's name and they acknowledge him as leader. Later, Alice warns Narumi that Renji had miscalculated because of Narumi and that he will come after him soon. Narumi goes back to his job helping with the concert and the day of the concert arrives. Narumi isolates himself and has the vocals of the band wear a replica of Renji's shirt to lure him out, which succeeds.

Narumi introduce an online game called Power Play Ball, or Powerebo for short. While he's at the arcade playing this game, a few men barge in, one of whom Narumi recognizes as Nemo. The men are trying to raise the rent for the arcade, which would likely lead to it closing down. Major argues against them, and they propose a gamble with the loser backing off, which Tetsu agrees to immediately. They point at a Powerebo machine and say they will use baseball to decide the winner and Major accepts. However, Major doesn't realize that they are talking about a real baseball game. Major starts to try to round up a team, and the Fourth shows up with some guys from the Hirasaka Group to fill up the remaining slots. Alice decides to become the coach for the team. The day of the game approaches, and Alice reveals that their opponents are quite the tough bunch. Narumi reveals to the rest of the NEETs that Nemo was formerly a baseball player.

The other NEETs ask Toshi where he's been and what he's been doing. He starts to cough, but pushes Ayaka away when she tries to help. Narumi goes out to talk with him alone. Toshi insults Ayaka a bit, but has another coughing fit and pulls out some strange pills. When asked, he calls it “Angel Fix” and wanders off. Narumi talks with Tetsu about it later, but Tetsu tells him not to tell Ayaka that her brother is taking drugs. The next day, Narumi walks into Alice's room to find Ayaka trying to fix up her hair, but she is kicked out when the Fourth arrives with a job. The Fourth is there to ask Alice about Angel Fix. Alice calls the rest of the NEETs up and Narumi tells them about Toshi having Angel Fix. They all set out to find Toshi, but the Fourth stops Narumi from helping this time. Later, Ayaka is grilling Narumi because she is being left out, which causes Narumi to remember what her brother said about being his replacement.
