Heaven's Memo Notepad

Ayaka is hospitalized and unconscious with low chance of recovery. Everyone is noticeably shaken with what happened until Narumi finally returns to the ramen shop, asking Tetsu to teach him how to fight properly. Narumi then asks Alice to help him, with her once again warning him about the burden of this knowledge. Alice tells him that she knows why she would want to kill herself, but doesn't know why she chose the school roof, which was too low to ensure death. Just like Narumi, Alice blames herself for not stopping Ayaka, but Narumi is able to comfort her. She then officially makes Narumi her assistant for this case. The next day, Alice orders Narumi to go to the greenhouse, where the Fourth is waiting.

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.

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.

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.

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.

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.
