Within a Hollow Heart - Chapter 47: Volume 1, : "Echoes of the Severed"

One day, when she was bored, Qingyun edited the scenes of herself marrying different heroines in various lines while playing fan games.

Who would have thought that it would then travel through, and the video appeared all over the world!

Game Hinata: Qingyun-kun, please take care of me in the future…

Hinata: ?G? So I-I will marry Qingyun-kun!

By the way, I mixed the original movie version of Naruto who was kissed by the ghouls several times by the villain.

Everyone: It turns out that Naruto likes the big sister.

Naruto: No, I’m not, I don’t…

besides.

Game Fireworks: Lord Husband, give me some advice for the rest of my life!

Hyuga Sunzu: Boy, you are not satisfied with marrying Hinata, yet you still…

At this time, the video showed Qingyun and Madara dancing, splitting the mountains and the ground, and transforming the map.

There is also Hinata Fireworks, and the sisters join forces to split the moon.

Hizu: … You know, the marriage contract of Hana is destined in the future, please respect the future.

15 years ago the world discovered magic as well as mythical beings (basically beings from various legends) in another dimension. Humankind learned to summon these dangerous mythical beings and use their power to great effect. Seven countries formed contracts with these “mythical beings” and gained their allegiance as a result. The mythical beings will choose their summoners on their 14th birthday and give them a stigma. Schools have been set up to train summoners and magical swordsman (basically bodyguards that give the summoners time to cast their spell) as a result.

15 years later after the finding of magic Kazuki Hayashizaki is chosen as a summoner and given a stigma to indicate that. This is surprising since males aren’t chosen as summoners due to their low amount of mana compared to females. As the first male to be a summoner Kazuki is under a lot of scrutiny by almost everyone.

To complicate matters his sister (who’s a magical swordsman) is against him going into summoner school to train there as a summoner. Because summoners and magical swordsman have a cat mouse thing going on where summoners look down on magical swordsman as inferior so his sister naturally is against him going there. She’ll stop him even if it means going to war.

Kazuki however is determined to thrive in summoner school and has already determined to give it his all. Even if he’s the lowest ranked student (ranked E) and his fellow students intend to demean him he’ll prove himself as the strongest summoner.

What was originally an ordinary day, suddenly became a historical turning point. Enormous, mysterious Cubes appeared all over the world without warning and as if Judgement Day’s spears, inserted themselves into the blue planet.

From inside the enormous Cubes, endless streams of monsters gushed out alike raging tides, utterly defeating the unguarded armies of each state in the blink of an eye.

In order for humanity to preserve its final embers, the heads of states issued orders of retreat, to no longer attack the Cubes but rather to cling to remote cities, which they turned into self-sufficient survivor bases and around which they built 100-meter-tall Walls of Life!

Many years later, while bearing the heavy weight of history, the first expeditionary force brought back a world changing piece of information. The Cubes possessed exceedingly high intelligence and they regularly transmitted mission instructions to humans nearby. The mission rewards were incredible.

Since then, humans rushed out of the confines of the walls and once more set foot on the wasteland!
