How Not to Summon a Demon Lord (Season One)

How Not To Summon A Demon Lord Title

Diablo is the demon lord from another world, living in a one-bed apartment with Rem and Shera who summoned him. Living with girls is not easy for this former shut-in gamer!

The Overview

Shut-in gamer, Takuma Sakamoto suddenly found himself in another world, summoned there by an Elf and a Pantherian who then tried to enslave him with magic. Luckily, he had been summoned as his gaming persona, Diablo and reflected the magic back at them. Of course, this now means that he’s stuck in a strange world with all of his powers and abilities from the game with two hot girls…

Diablo, however, suffers from social anxiety and being close to a girl would be hard enough, but now he’s forced to live with two of them and there’s only one bed! Each has their own reason for summoning him there and now it’s up to Diablo to help his new friends, especially as he appears to be the most powerful person in the world!

The Story

This series is split into two main stories, the first involving Shera and her desire to leave her royal life behind her to make it on her own, and the second following Rem and her attempts to remove the soul of the demon lord Krebskulm from within her. There are a number of smaller side stories but they all have a purpose and help to drive the main stories along. It’s actually a very well constructed and delivered story where nothing feels unnecessary or out of place. There’s definitely more to this than just the ecchi content.

The Characters

How Not To Summon A Demon Lord Episode 6 Diablo's Flow Of Magic

Diablo is the central character as the story is about how he handles with being summoned to the new world. We get a lot of his internal dialogue which focuses on how he’s going to navigate various social interactions. These are some of the most enjoyable moments in the show and it really grounds Diablo, making him relatable. It also means he can play the edgy demon lord and the nice guy harem protagonist at the same time.

How Not To Summon A Demon Lord Episode 4 Shera Boobs

Shera is the bubbly Elf with the big jiggly boobs, but there’s more to Shera than just being really, really good looking. She also has a gentle heart and is far more compassionate than it may appear. Her ability to see magic meant that she knew about Rem’s affliction long before she found out exactly what it was and still stuck with her. She’s also playful and has a real lust for life which exhausts Diablo, but I think she’s great.

Rem is the moody Pantherian with the athletic body. She is the brains of the due and even though she’s smaller than Shera in many ways, she more than makes up for it with her sharp tongue and kind nature. Another of my favorite things in this series is the way the Rem and Shera grow closer and closer as friends.

How Not To Summon A Demon Lord Episode 11 Alicia is Evil

Alicia is the bespectacled knight with the impressive chest plate armor. She’s also the one character that goes through the most growth in the series. Her darker side leads her to betray Rem, but it stems from her loneliness which is something Diablo can relate to. It’s a lot of fun watching Alicia as she slowly reveals her true nature throughout the series.

How Not To Summon A Demon Lord Episode 3 Edelgard

Edelgard is the leader of the Fallen army with the killer body. She attacks Diablo head-on and lived to tell the tale of it, which is more than most can say. When her plans with Alicia fall through, she takes the brunt of the Fallen’s attack to save her. It’s a big turning point for her and Alicia, but we won’t find out too much more until we’re blessed with a second season.

How Not To Summon A Demon Lord Episode 5

Sylvie is the diminutive Guildmaster with the floppy ears and fluffy tail. She’s one of the only characters to talk to Diablo with ease, often having fun at his expense, but she also knows when to hold back. Unfortunately for her, she also got Diablo drunk and found herself being used as a body pillow. I would like to see more Sylvie for sure.

How Not To Summon A Demon Lord Episode 10 Clem Loves Cookies

Klem is the underdeveloped form of Krebskulm and she loves cookies. She’s not in it much, but her violent outburst and childish nature make her pretty entertaining. Her endless supply of mana is also helpful when recharging Diablo, which is something she also seems to love doing.

Fan Service

It falls short of series like High School DxD and Sekirei in terms of fan-service, but it is still hot as hell. There are no nipples which is the big difference, but it has more than enough fan-service to keep things interesting. For example, there are several great moments like the time Diablo tried to unlock Shera’s slave collar or whenever the girls help Diablo to replenish his MP. All of the girls are varied which means there should be someone for everyone.

Ecchi Highlights


Story Rating: Great

I think the story in Demon Lord is actually very well crafted. It does a great job of foreshadowing and makes sure that you aren’t surprised in a bad way. There’s a lot of character development and it shows, making them relatable and interesting. In the whole series, there are very few dull moments and it’s always exciting when Diablo gets angry.

Ecchi Rating: Hot

We’re introduced to some of the most memorable characters in the ecchi harem genre. It helps that they are all so different and stunningly beautiful. Shera’s boobs are probably the star of the show and have a life of their own. Just check out the OP for an example. It’s not as in your face as Why the hell are you here, Teacher!? but that’s not necessarily a bad thing.


How Not to Summon a Demon Lord is a fun series with an engaging story and relatable characters. It’s also hot! Like there are some seriously hot moments and I haven’t even mentioned the most “shocking” moment. I loved this series and will continue to hold out for a second season. It really has a great balance between storytelling and hot bouncing bodies.
