I'm not sure specifically as I haven't read it. But generally, it might be about a character's journey to becoming a legend over the course of a decade.
Power and its consequences could be a theme. As the character gains power over the decade and becomes a legend, there are probably implications of how that power affects them and those around them. Also, the theme of friendship or relationships might be present. Along the journey to becoming a legend, the character may have made allies or had relationships that influenced their path.
There's 'That Time I Got Reincarnated as a Slime'. In this light novel, the main character, who starts off in a rather unassuming state, gradually becomes a powerful and legendary figure. It shares the concept of growth and achieving a legendary status over time, which could be related to 'I became a legend a decade later light novel'.
Tsukasa Kadoya, who is Kamen Rider Decade, is a key character. Then there are the other Kamen Riders from different worlds that he encounters. For example, Kamen Rider Kuuga. Their interactions with Decade shape the story. Also, Natsumi Hikari plays an important role as she is often involved in Decade's adventures and provides a different perspective compared to the more combat - oriented Decade.
One of the main storylines often involves the journey of the Kamen Rider Decade through different Rider worlds. He has to face various challenges and foes specific to each world he visits.
Often, 'Decade Love' light novels would likely have a long - term relationship development. The characters' personalities and their feelings for each other change and mature over time. For example, they might start as strangers or acquaintances and over the years, their love deepens and becomes more complex.
I'm not very familiar with this specific light novel. It might be about a character who experiences a bite of some sort and then ascends to the throne. Maybe it's a fantasy story where the bite imparts some special power or curse that leads to his kingship.
After transmigrating, you can refer to the following classic novels:
" Startling Step by Step "-A Qing Dynasty novel about a modern girl who traveled to the Qing Dynasty and became the concubine of Emperor Yongzheng. She experienced the struggles of the palace and the political games.
2 "Palace Heart Locking Jade"-Modern novel tells the story of a modern girl who traveled to the Qing Dynasty to become Kangxi's concubine and experienced all kinds of trials and challenges in the palace.
3 " Hua Qian Gu "-A modern novel about a modern girl who traveled back in time to become the concubine of Emperor Xuanzong of the Tang Dynasty. She faced power struggles and love entanglements in the palace.
These were some of the more popular time-travel novels where one became a concubine after transmigrating. Of course, there were many other types of transmigration novels that could be chosen, such as fantasy, science fiction, and so on.
