Dreamwalker: Reign of the Heavenly Sovereign! - Chapter 2 (r18)

An unnamed 34-year-old Japanese NEET is evicted from his home following his parents' death.

Upon some self-introspection, he concludes that his life was ultimately pointless.

Walking down a street he intercepts a speeding truck heading towards a group of teenagers, in an attempt to do something meaningful for once in his life he manages to pull one of them out of harm's way before getting himself in the way of the truck and dying.

Awakening in a baby's body, he realizes he has been reincarnated in a world of sword and sorcery.

He resolves to become successful in his new life, discarding his past identity for his new life as Rudeus Greyrat.

A world from another dimension suddenly appeared in the Milky Way galaxy and collided with the earth. A spatial collapse occurred, which allowed the monsters crossing over from the other side to invade various countries, and the earth fell into great calamity.

The military was powerless against the invasion because modern weapons didn't work against monsters from another world. Under the desperate situation, a god-like figure appeared and bestowed blessings upon the humans to awaken their power. From then on, the earth regained its hope, and these extraordinary people were called Realizers.

Tenku Okuihara is a five-year-old boy who dreams of becoming a Realizer to protect the world and his family. But an incident changed his life goal from a hero to a grim reaper.

After finishing playing mahjong, Yu Zhou, a recently resigned writer, returned home and found a young lady from ancient times, Xiang Wan, who was a former prime minister’s daughter, sitting on her sofa. After some simple communication, Yu Zhou, with her adolescent mind, accepted this “roommate” who had traveled through time.

On the other hand, Yu Zhou’s novel was adapted into an audio drama, which was unexpectedly performed by the well-known voice actor Su Chang, causing Yu Zhou to be overjoyed yet also in tears, because Su Chang was her ex-girlfriend.

Through their new connections, the girls re-examine their own lives and achieve personal growth. This absurd yet realistic experience may also “pat awake” Yu Zhou’s stagnant love life.
