In the year 2050 on earth there was an Incident that changed the History of Mankind.

Ryuga Isimiya is an otaku and a high school graduate in Japan like everyone else. He is a person who does not like violence, but something that will transform him into an important figure of two Worlds.

The Ryuga family lives in Tokyo and the three people are Lina Isimiya Ryu's mother, her sister Aoi Isimiya and Ryuga himself, while Ryu's father had died while performing the Conquest of the S+ Dungeon Rank A Week ago.

40 Years ago there was an incident that changed history on Earth.There was an earthquake and appeared a strange portal that issued terrible monsters throughout the World.

Everyone ran in fear as they saw the monsters coming out of the Portal attacking and slaughtering humans to serve as their food.

Blood splattered

everywhere, many buildings were destroyed and burned, fear struck everyone, the world was in chaos as if to be the end for man.

But when everyone was desperate.

Humans received a resurrection and gained the power to fight monsters that came out of the Portal.

After that incident humans began to strive hard to fight the monsters that came out of the Portal.

The portal that took out those monstrous monsters started to be called Dungeon by everyone because after Portal appeared, the portal could be entered and inside was the Dungeon Boss.

If you defeat the Dungeon Boss then the portal will disappear, but it is not that easy because before fighting the Dungeon Boss it will be blocked by other monsters. Dungeons themselves have various levels, namely:

•________________________________________________________________________________

In 2080 at

Earth

A week after Ryuga's father's death

Heavy rain is pouring down on Tokyo.

A young man walks towards a public cemetery.

Under the swift rain with a sad face.

Ryuga stood staring at his father's tombstone.

"If I had been training to be a Hunter and to be strong maybe this wouldn't have happened" Ryu said softly under the moans of rainwater with slightly shaking lips.

Regret gets into Ryu's feelings.

Ryuga actually got a resurgence when he was 7 years old. While people generally get a revival at the age of 15 years, but Ryu is not interested in the name of strength. He thinks strength can only lead to violence and he doesn't like that.

Ryuga regretted never training his strength. Ryu every day just watch anime, read manga/novel as otaku, and of course learn general knowledge.

Ryuga is a genius and intelligent boy. Ryu can memorize and remember anything only once.

"I'm a genius?, but why am I a genius but can't protect the people I care about!!" Said Ryu shouting in tears and determined to be strong.

In a room that was all white, a middle-aged man in white clothes was laughing loudly.

"Hahahaha finally the filler of my boredom all this time has risen." the middle-aged man laughed happily but clearly saw a sinister smile on his lips.

**

Ryuga opens the door.

"I'm home." Ryu did not get an answer from his mother and sister felt strange because the mother and her sister were at home.

After a while Ryu searched and there was really no one at home.

Drrr drrr drrr

Ryu's HP rang and he picked up his phone.

"Nobody where are you." Aoi her sister said in tears.

"Sister's home, what's up Aoi? Why are you crying." Ryu said in an anxious tone.

"I-mother sister..."

"Mother why?"

"Mom will never wake up again." Aoi was crying so much.

Pyarrr

The sound of HP falling.
