I Couldn't Become a Hero, So I Reluctantly Decided to Get a Job Season 1

Raul Chaser, the main character, is shown training to be a hero alongside Airi "All A", among others. At the end of the session they find out that another hero has defeated the Demon Lord and there is no longer any need for them to train.

Raul tries to teach Fino how to greet customers properly, only for her to misspeak and end up scaring customers away, frustrating both of them. He later has a brief encounter with Airi who becomes angry at him for forsaking his dream to become a hero.

The workers at Leon receive a strange product, and everyone tries to figure out how to work it. When Fino attempts to help, her body releases too much magic, causing the product to go out of control and a number of appendages extend from the product ensnaring Airi, Fino and Nova.

Lawson, the convenience store next door to Leon, needs an extra worker for a day, so Elsa, the manager, comes over and asks to borrow one of the Leon staff. Seara, the manager, volunteers to go but is prevented by the assistant manager.

Leon experiences a downturn in sales due to the big new magic store, Amada, opening in town. Since they are having a slow day, Raul and Fino go undercover on the manager's orders to see what all the fuss is about.

Airi was a straight A student in hero school and is embarrassed to have to admit that she is working as a bunny-girl at the rival magic store. She gives them a tour of the store and is relieved to learn that Fino is only pretending to be Raul's girlfriend.

Fino and Raul arrive to find that the old woman's son went to Amada and bought a unit too. Because the Leon unit is more expensive, the son wants to install the unit he bought and they are about to leave but stop when the son flags them down.

Nova has collapsed due to heat exhaustion since the store's A/C has broken down. The Leon head office has sent a shipment of summer goods, but, due to the heat wave, customers are staying home. Fino, leaking magic because of the heat, sets off a box of fireworks and scorches her clothes.

Payday has arrived and Fino is given her first pay check. Seara suggests that Raul escort her as she goes shopping for the first time. Fino is nervous about the experience but after she gets through the first few transactions, she gets the hang of things.

Fino has been acting a little out of character since the attack in the last episode, and Raul is worried about her. When he presses Fino on the issue, she tells him that she has decided to work harder so that she can become the manager of the Leon store that she intends to open in the demon world.

Raul Chaser finds out where Fino is taken and goes to rescue her at the old Heroes Academy. Once there he faces Blaze and defeats him using only a ruler. As he tries to rescue Fino, Airi interrupts and states that she will kill Fino because demons killed her family.

Raul, Lami-san, Lore-Senpai, Airi and the old man that come in to buy light globes sets off after Fino. As they go towards the mountain they start getting separated. At the end Raul faces Fino in a battle.
