It could be. There are some stories based on real events that might seem like the garbage barge story, but it's hard to say for sure without more details.
There was a family who decided to go living garbage - free. They first analyzed their waste. They found that a large part was packaging. So, they started buying in bulk and using their own reusable containers. For things like coffee, they bought beans and ground them at home. They also made their own cleaning products, using simple ingredients like vinegar and baking soda. This way, they reduced their garbage production to almost zero. They even inspired their neighbors to follow suit.
The 'garbage hero light novel' could have a very diverse plot. It might be about a hero who is initially underestimated or considered worthless like 'garbage' by society. He or she then embarks on a journey to prove their worth. Maybe they discover some hidden power within themselves that is related to the 'garbage' concept, like being able to recycle negative energy into positive power. Or it could be set in a post - apocalyptic world where resources are scarce and the hero has to scavenge among the 'garbage' to survive and save others.
I'm not sure specifically what 'garbage night graphic novel' is about as there could be many different stories with that title. It might be about events that occur during a night related to garbage, perhaps with some strange or interesting characters in a graphic novel format.
I'm not sure specifically as there could be many 'angry garbage man' stories. It might be about a garbage man who is angry because of long working hours, unfair treatment, or maybe difficult working conditions.
The term 'garbage time light novel' is quite ambiguous. It could be that the 'garbage time' refers to a time in society that is considered useless or wasteful. The light novel could then be centered around characters who are living through this 'garbage time', facing various challenges, or perhaps finding some sort of meaning or adventure within what is generally regarded as a 'bad' time.
I recommend the novel,"A Hundred Ways to Become Immortal." The male protagonist was considered a waste. He bought all kinds of waste all year round, including waste pills and low-grade materials. However, he was not picky. As long as he could be recycled, he would not let go. Through continuous acquisition and cultivation, he eventually became a top self-cultivator in the immortal world. I hope you like this fairy's recommendation. Muah ~😗
