Kiyotaka Narumi, a world-class detective, has been missing for two years. His last words prior to his mysterious disappearance were "I'm going to uncover the mystery of the Blade Children." These words have haunted Kiyotaka's younger brother Ayumu ever since, but neither he nor anyone else has gotten any closer to figuring out their meaning. But after Ayumu becomes the prime suspect in a murder, he begins to discover people with links to the 'Blade Children' all around him! Following in his brother's footsteps, Ayumu now must begin his own investigation into the mysterious Blade Children...
Although these mangas seem different on the outside, they are remarkably similar. For one, Spiral, has Narumi Kyotaka, younger brother of a missing detective, whose last words was "blade children." This leads to an action pack, danger filled, battle field of the minds, where characters interact, and sides are switched, and who and what to trust is the question you ask every single second. On the other hand, Bloody Monday, has Fujimaru Takagi, son of missing VP of the public security Investigative Division, whose last words were “bloody Monday. “This leads to the exact same feeling of danger, action, and characters crossing sides, while circling around a great astounding mystery.
Although the story lines are completely different, the feelings the characters gives and the satisfying mystery are the same. If you love one, you will love the other.
There are two worlds which exist side by side – the ordinary surface world of the humans and the secret world of ninjas called Nabari. Within this secret world, the opposing ninja groups are fighting over who should possess the ultimate power known as Shinra Banshou. Enter Miharu Rokujou, a high-school student who lives a carefree life and likes to keep himself to himself. Unfortunately for Miharu, his carefree life is about to be over, because within him is hidden the ultimate power and there is no end of evil minions ready to kidnap him for it! Miharu’s only chance of survival is to embrace this mystic world and become the King of Nabari himself. With the help of his new ninja friends, Kouichi, Shimizu, and Kumohira, can he come to grips with his powers or will he fall prey to his many enemies instead?
Despite the premise not being too similar, both Spiral and Nabari No Ou function very much in the same way. They confront serious plot points that are very grave while joking around and often minor characters play key roles at intense moments. Adding to this, the protagonists are not identical but VERY similar; both doubting of themselves and both naturally skilled beyond belief.
If you like a convuluted plot and interesting characters each with their own goals and dreams then both of these are good reads. They're by the same author and you can tell by how the plot keeps moving and changing.
I never thought I would like the mystery genre until I watched and read Detective Academy Q, but I was wrong. Detective Academy Q has a great story line and great characters. Its two main characters, Kyu and Ryu are both awesome and geniuses in their own right. And it has amazing, amazing myteries that are complicated yet not quite unsolvable for us at home. In fact, you could say it has it all. When I read Spiral afterwards, however, I realized Academy Q had met its match. Everything and I mean everything that I mentioned above can be seen in Spiral, although Spiral has a bit more action in it. But one thing for certain is, if you loved Detective Academy Q, you will definitely love Spiral. And likewise, if you liked Spiral, I would highly recommend you read Detective Academy Q.
