Ep 10. No, That Will Explode

Ayumu is spending his day with his three lovely roommates. Haruna and Eucliwood are occupied with their own work, and Sera is showing Ayumu around town - she has ulterior motives which we will come to know of soon.

As the day proceeds, it turns out that someone is after Ayumu's life - he is attacked several times by mysterious individuals. Although he is saved by Sera, Ayumu cannot help but wonder who these people are, and why are they after him.

Meanwhile, Haruna and Eucliwood are trying an experiment. They are creating a potion that would enable Ayumu to access his powers without transforming into a zombie. While working on it, they inadvertently mix a Deadly Magic spell into the potion, and the entire lab explodes!

Fortunately, no one is hurt. However, they are horrified to see that the potion has spilled over Ayumu's body, and he is left in his weakened zombie state - but this time he is self-aware and has a human-like intelligence! Ayumu is elated at this development; finally, he has the power of a zombie without all the undead baggage.

As they try to adapt to the new situation, Ayumu is still being attacked by strange individuals. Haruna and Eucliwood try to find out why Ayumu is being targeted but cannot seem to figure it out. While they are deliberating, Sera cooks up her plan - she reveals that she is part of a group of vampire ninjas tasked with protecting people like Ayumu.

The group is after a serial killer named "The Teacher," who has attacked several individuals with the power of a Necromancer. Those under a Necromancer's spell are mind-controlled and become his puppets. The Teacher has his eyes set on Ayumu because he believes that Ayumu has the power to destroy him.

As the group decides the course of action, Ayumu tries to interact with his new state of undead intelligence. He discovers that his newfound intelligence has made him a genius when it comes to solving complex equations and programming languages.

While Ayumu is enjoying his new metamorphosis, the group comes under attack. The Teacher has succeeded in his latest attempt to control someone under his spell - this time it’s Haruna. With her strength and power, she becomes the biggest threat to the group. Ayumu must find a way to stop her without hurting her, for he knows that she is under The Teacher's spell.

Ayumu devises a plan, and with the help of Sera, he manages to free Haruna from The Teacher's control. But the group is not done yet. They must find out where The Teacher is hiding and put an end to his reign of terror. They embark on a journey to the nearby abandoned warehouse, where they believe he is hiding away.

What follows next is a series of intense battles, mind-games, and deception. The group is determined to stop The Teacher, but he seems to be always one step ahead. Ayumu, with his new powers, emerges as a potential threat to him, and The Teacher does everything he can to stop Ayumu.

In the end, there is a high-voltage, explosive battle - not just between Ayumu and The Teacher, but also between the forces of good and evil. The fate of the world hangs in the balance. With lives on the line, it’s Ayumu's newfound intelligence that saves the day - and puts an end to The Teacher’s evil schemes once and for all.

As the series ends, Ayumu returns to his normal state - he is back to being an undead zombie. However, he values his time with his newfound intelligence and will use it to help the people of the world. Who knows what other surprises are in store for him as he embarks on his new adventure?
