Isekai Office Worker is a Japanese BL anime series about an ordinary man who gets whisked away to a magical fantasy world. The main character is your average office worker. On his way home, he tries to save a teenage girl from danger. Instead, they both end up in a parallel universe. Now, the protagonist is trapped in this unfamiliar world, where he takes a job as an accountant. He develops a close relationship with a handsome knight.
It's rare to find an anime that combines a fantasy adventure with a proper gay romance, but Isekai Office Worker delivers both! I love the clever protagonist. He uses his intelligence and social awareness to stay alive in an unfamiliar world. While the art quality looks mediocre, I like that we see the couple show so much physical affection. Their romance gets quite naughty. However, the love interest becomes overprotective and annoyingly possessive.

Plot
Seiichirou is transported to a magical fantasy world.

Seiichirou Kondou is an ordinary office worker approaching his thirties. He's a notorious workaholic whose life revolves around his job. Even on his day off, Seiichirou shows up at the office and works late into the night. One evening, Seiichirou is heading home when he hears a girl screaming for help. He rushes over and spots a teenager named Yua being dragged into a mysterious portal. Seiichirou grabs her hand, hoping to pull her to safety. Instead of saving Yua, he gets sucked into the portal with her!
Seiichirou and Yua find themselves in the Kingdom of Romany, a fantasy world where people can perform magic. The kingdom's inhabitants used a special spell to summon Yua from another world. Yua is the Holy Maiden with extraordinary magical powers. Every hundred years, a mysterious forest unleashes a deadly miasma that threatens the kingdom. Only the Holy Maiden can purify this dangerous substance and save everyone from disaster. With another crisis approaching, the kingdom has summoned Yua to help them. However, they only intended to summon Yua. Seiichirou is an unfortunate bystander who got caught up in the spell.
Nobody expected Seiichirou to show up. There's no way to send him home. To make up for this mistake, Prime Minister Karvada promises to take good care of their unexpected guest. The kingdom will provide Seiichirou with food and shelter, so he can live comfortably in this unfamiliar world. When asked if he needs anything else, Seiichirou has an odd request. He wants a job! Even after getting transported to another universe, he's obsessed with working. Seiichirou gets a job as an accountant at the royal palace. He befriends his cheerful colleague, Norbert Blanc.
Seiichirou must get used to life in the kingdom.

Before long, Seiichirou is buried under mountains of paperwork. His inner workaholic has been unleashed! He takes on more assignments than anyone else. After noticing how exhausted Seiichirou looks, Norbert recommends a special nutritional tonic. Unlike an ordinary energy drink, this magical potion can give people an instant boost of energy. Seiichirou tries one and discovers that it works wonders! Soon, he's hooked on these tonics. With his newfound energy, Seiichirou can work even more hours than before.
Seiichirou gets a chance to catch up with Yua. She's settling into her new life quite comfortably. Prince Yurius has been treating the Holy Maiden like royalty, making sure all her needs are met. She has an entourage of handsome knights looking after her. One of her protectors is Aresh Indolark, the youngest knight commander in the kingdom. Aresh comes from a noble family and has a talent for magic. Despite his serious personality, he takes his duties seriously. Currently, Aresh is helping Yua practice the spells she'll need to purify the forest. With everyone counting on her to save the kingdom, Yua is eager to fulfil her destiny.
During a private chat, Seiichirou reminds Yua that they were brought here against their will. They're both hostages! Yua doesn't appreciate Seiichirou's warning and throws a tantrum. Their disagreement causes a stir around the palace. Meanwhile, Seiichirou continues throwing himself into his work. He drinks even more magical tonics to keep up with his demanding schedule. One day, his body collapses. Fortunately, Aresh finds him just in time and uses magic to save his life. After this incident, Aresh always checks up on Seiichirou and reminds him not to work so hard.

Isekai Office Worker Review
Review
Anime Review Score: 8.3

It's a truth universally acknowledged, that an anime in possession of a creative plot, will avoid BL content to appeal to a bigger audience. Oh, you wanna see the two leads become boyfriends? Sorry, the best we can offer is a little ambiguous fanservice! Then, Isekai Office Worker comes along and breaks the damn rules. It gives us a nearly 50/50 split between exploring its magical world and developing the gay relationship. Finally, an anime that does both! We deserve an elaborate fantasy story AND a proper same-sex romance.
Seiichirou isn't your typical fantasy hero. He's an ordinary office worker trying to survive in a dangerous world. Magical powers? None. Fighting skills? Zero. Instead, he relies on his intelligence and social awareness to stay alive. My favourite part of the story is hearing Seiichirou's inner thoughts. He analyzes situations and studies the people around him to plan his next move. It's like watching someone play chess while explaining the strategy behind every decision. When he makes an interesting observation or comes up with a clever plan, I'm so impressed! I love seeing Sei outsmart everyone and wiggle himself out of trouble.
The naughty scenes happen early! By Episode 2, Seiichirou and Aresh are getting physically intimate… Wait until you hear the ridiculous reason they end up in bed together. Sei has fallen seriously ill, but the only cure is Aresh's magical penis. I'm not kidding! Have sex or die! For the rest of the series, Seiichirou must keep riding that dick to replenish his health. WTF??? I dunno whether to laugh at this bizarre medical treatment or question the ethics behind it. I'm sure someone online has already written a scathing thinkpiece about this anime's consent issues.
After the first few touchy-feely scenes, my initial shock wears off. Hooking up becomes part of Seiichirou & Aresh's routine, almost like filling up your car at a gas station. Put it in and start pumping! They're always kissing or touching for "magical" reasons. Whatever you wanna call it, I like that their intimacy happens regularly. It's great to see an anime where two men are so comfortable showing physical affection. But it's not just about getting laid! I also enjoy the couple's conversations. They're curious about each other and want to understand their partner better.
Seiichirou is a hardcore workaholic who never wants to stop working, even when Aresh keeps telling him to rest. Their squabbles are funny at first. As the romance progresses, Aresh becomes overbearing. He throws a hissy fit when someone acts a little too friendly with his man. Relax! Nobody is stealing him from you! Aresh also makes big decisions without consulting Sei, like buying a house and forcing them to live together. Ugh, his possessiveness gets on my nerves! I wish Aresh had more depth as a character beyond being hopelessly obsessed with Seiichirou.
Despite all the sex scenes, Isekai Office Worker isn't as racy as an 18+ anime series. Sorry if you were hoping for some magical fantasy porn, but nothing gets that explicit! Even so, the series spoils BL fans with plenty of steamy visuals. Sex in Episode 2! Kissing in Episode 3! And by Episode 4, Sei is straddling Aresh's lap! The physical affection declines toward the end, but there's still more gay stuff than most anime would ever dare to show. Sadly, the art quality is mediocre. The couple's intimate moments usually turn out fine, but other scenes can look rough.
Isekai Office Worker has interesting storylines and plenty of quirky characters. I love following Sei's adventures around the kingdom. But is the plot really that special? Nah, it isn't in the same league as the best anime out there. Okay, but how many of those mainstream series let their male hero make out with a handsome knight? Big fat zero! Isekai Office Worker fills a rare niche by giving us a decent fantasy story with a sexy gay romance. Do you know how hard it is to find an anime that delivers both? As a BL fan, I'm gonna cherish this combo whenever it comes along!
Summary
Clever story
I'm surprisingly invested in the royal politics of this magical kingdom! Seiichirou is my kind of protagonist because he's always thinking two steps ahead. I enjoy seeing him outsmart everyone.
Touchy-feely romance
Sei and Aresh are so affectionate. They get really touchy-feely. I like how the couple's physical intimacy happens regularly, even if they pretend there's a "magical" reason for them to kiss or have sex.
Mediocre visuals
Some of the artwork is so barebones that I wonder if the team was rushing to meet a deadline. The intimate scenes usually turn out fine, so at least they know which parts of the anime deserve attention!
Happy ending
Isekai Office Worker has a happy ending. Seiichirou solves the church mystery and catches the culprit. I'm a bit disappointed that the romance stops being the focus during the final episodes.
Steamy style
This anime spoils BL fans with plenty of kissing and intimate moments between the two leads. It's not quite gay fantasy porn, but we're getting way more action than most mainstream anime!
83%
Isekai Office Worker offers a decent fantasy story with a sexy romance. I like how the gay couple is so comfortable with physical intimacy, which you'll never find in a mainstream anime series.
