[GIRLS BAND CRY + Lonely Rock + MYGO + JOJO's Bizarre Adventure, a semi-original work (original characters) (no system) (first-person perspective) (slightly humorous) (protagonist has some flashbacks)]

(This is the author's first work, and you can clearly see that his writing has gradually improved.)

A former professional rock musician suddenly arrives in this different world, starting his dream anew, meeting new companions and like-minded friends, and encountering many unexpected events.

A new beginning, a new starting point, new goals. The early episodes will include flashbacks of the protagonist's past, but these will stop later.

A 32-year-old single man wins the title of "champion of all-nighters" and is rewarded with a "reincarnation package," leading to his encounters with various beautiful young women. (The story continues...)

A young girl's blush speaks louder than any sweet words; sister, please put the stick down first.

Who has offended this living father again...?

Does anyone know the emergency number? I want to call the police...

Jingyu: So nobody knows?

Everyone: They know but won't say anything.

Upon waking, Nobita finds himself sixty years behind in technology. In the town of Tsukimidai, all memories of Doraemon vanish along with the regressed era. After a series of twists and turns, Nobita and his friends learn the truth: an unprecedented, massive, and trans-temporal war is unfolding, its target the future where humanity's technology is booming. The dominoes hidden in the past have already fallen, about to form a colossal wave that will engulf every era of humanity. The only clue is a snapshot taken across time. On September 19, 1492, at the center of the temporal vortex, the Time Police captured a photograph of the back of a blue nursing cat-shaped robot. This becomes the catalyst for Nobita and his friends being drawn into this trans-temporal heist. As they uncover more and more clues across different eras, a massive conspiracy gradually surfaces.
