NEET Received A Dating Sim System Part 1 (ch.1-200)

Chapter 171 - First Blood!

"They're here! Haruta-kun, activate your Astral Vision!"

Seiji instantly activated [Astral Vision] upon Natsuya's reminder.

He actually hadn't mastered this spell yet. He was casting it with his bonded spirit's assistance.

Seiji's eyes instantly turned blue, and everything within his field of vision was also tinted blue. The world around him became much sharper; it was as if he were wearing high-tech night goggles.

[Astral Vision]... This type of vision rendered the school in a completely different light.

Spell formations of various sizes were engraved on each of the school buildings, and some were revolving slowly. All the spell formations were radiating differently colored light.

The largest spell formation was on the school grounds. It was so large that it exceeded the boundaries of the school grounds, and even with his enhanced vision, it was impossible to see it entirely.

Apart from the formations, there were many other defensive measures: interlinked chains which hovered above the ground; strange, totem-like objects; and flying lanterns, dolls, talismans, and sheets of paper. There were also a variety of other mysterious objects that were either flying in midair or following fixed paths. The chaotic scene made Seiji feel dizzy.

But what stood out the most of all were the various demons and spirits either guarding specific locations or roaming around.

There was a huge, large hammer-wielding one-eyed monster with green skin and a bald head.

There was a pitch-black demon that looked like a growth of aquatic weeds, and its many tiny eyes were opening and closing rapidly.

There were a team of skeletal warriors clad in tattered armor and wielding rusty weapons—Seiji assumed these were grudge-bearing ancient spirits from some battlefield.

There was a smooth, completely white abnormal-appearing demon.  It was lanky, and in the place of legs and arms, it had four sharp blades. It lacked any facial features, and its head was also blank, save for a black talisman attached to the top of its skull.

...

Witnessing all these sights was a truly eye-opening experience for Seiji.

Many of these entities' appearances were inside of his expectations and were rather normal, while others seemed incredibly out of place.

There were a few that he really wanted to comment on—especially that smooth, white demon. Seiji felt that without that talisman on top of its head, it would belong in a horror movie rather than a mystical school!

There were far too many different types of demons and spirits for him to ask Natsuya about, which was why he didn't ask anything. There would be plenty of time to chat after the duel.

At any rate, under [Astral Vision], the school was far different from how ordinary people saw it. Only after he personally witnessed this sight did Seiji finally realize what the president had meant by calling the school her "castle."

This was indeed Natsuya's castle with her as its Yin-Yang Master; this was indeed her well-defended territory.

However, the castle was currently under siege.

A huge number of demons approached both from the ground and the air!

The majority of them were red-skinned demons sporting horns and wings—they were the same type that Seiji saw when he was dispelling the amnesia spell on Shika.

This time, there weren't a ridiculous amount of demons like in the soul layer, but there had to be at least several thousand pouring towards the school like an unstoppable tidal wave.
