It might be a game-themed light novel. These sometimes feature characters who can summon units as part of strategic gameplay within the story's world.
Perhaps it's a light novel in a post-apocalyptic setting. The MC could summon units to protect themselves and others in a harsh, dangerous world.
It could be one where the MC has unique powers or skills that no one else can match. Maybe they were born with immense strength or gained it through intense training and rare opportunities.
There are quite a few. One example could be 'The Dungeon Master's Chronicle' where the MC is a sentient dungeon with its own unique abilities and challenges to overcome.
There are several. One example could be 'The Reborn Hero's Love for the General', where the MC reincarnates and develops a deep affection for the general.
There are several. One could be 'Trapped in Fantasyland' where the MC gets stuck in an RPG-like world full of magic and quests.
Maybe it's a mystery-themed light novel where the MC hides in the shadow to solve crimes or uncover secrets. The shadow could be a metaphor for their hidden identity or their way of operating unseen.
The MC usually goes through a whole new world with unique challenges and opportunities. They might have to adapt to a different body or social status.
Well, there are many. One example could be 'The Rising of the Shield Hero'. The MC in that starts off pretty weak but grows stronger over time.
A novel with an MC having light Xianxia could present a story where the MC's powers are used for good deeds and to bring positive change. The plot might involve quests or adventures that are not overly violent or dark, and the MC's journey is more about inner wisdom and kindness.
There's 'The Ancient's Tales' where the MC is a wise old man. The story focuses on his wisdom and how it influences the events and characters around him. It's a great read if you're into this kind of character.
Another aspect is prior knowledge or experience. In some light novels, the MC is reincarnated or transferred from another world. Like in 'Konosuba', Kazuma has knowledge from his previous life which he uses to his advantage in the new world, and this knowledge combined with his unique skills makes him overpowered in certain situations.
