My Thoughts on Shinmai Maou no Keiyakusha

Alright, let's dive into "Shinmai Maou no Keiyakusha," also known as Testament of Sister New Devil. This series definitely sparked some strong opinions, and after considering everything, here's my take.

First Impressions

Going in, I knew this was a blend of action, comedy, and a heavy dose of fan service, so I wasn't expecting a groundbreaking narrative. The premise itself – a hero tasked with protecting (and forming a contract with) the Demon Lord's daughter – felt like a fairly familiar setup. However, I was curious to see how the series would handle the balance between its various elements.

What Works Well

For starters, the ecchi content seems to be a major draw for many readers, and I can see why. It's apparently well-executed and integrated into the story, rather than feeling completely gratuitous. The main character, Basara, also gets some love. Unlike some harem protagonists, he's not a complete pushover. He's proactive, willing to protect those he cares about, and isn't afraid to get his hands dirty, even if it means killing his enemies. This willingness to act, combined with his responsibility towards the girls in his life, makes him a more compelling character than the average dense harem lead. The harem ending is also a plus for those invested in the relationships.

Areas of Concern

However, the combat and overall plot seem to be weaker points. Some readers found the fight scenes repetitive and predictable, with the hero barely scraping by each time. The power scaling also seems inconsistent, making it hard to feel invested in the stakes. Furthermore, some felt the plot was secondary to the fan service, and that the focus on sexual gratification detracted from the story's pacing. While Basara is generally liked, some feel his "hero complex" leads to cringy moments and that his strength doesn't always back up his bravado. I also noted the side characters didn't leave much of an impression on some readers.

⚠️ Spoiler Warning

There are minor spoilers in some reviews. One mentions Basara killing a character by giving him to another character to torture. Another brings up a potential incestuous relationship.

Final Verdict

Overall, "Shinmai Maou no Keiyakusha" seems to be a series that knows its audience and caters to them well. If you're looking for a complex, intricately plotted fantasy, this might not be your cup of tea. However, if you enjoy well-done ecchi, a proactive protagonist, and a harem dynamic with some action sprinkled in, then it could be an enjoyable read. I'd recommend going in with realistic expectations and knowing what you're signing up for – a fun, fan-service-heavy romp that doesn't take itself too seriously.

Synopsis

The most powerful contractor’s desire action drama begins!
