Power and its corrupting influence could be one main theme. In many light novels, the concept of power, especially when it comes to magic in this case, often leads characters down different paths, some good and some bad. Another might be survival, as the idea of a death mage implies dealing with dangerous and often life - threatening situations.
I think friendship and isolation are key themes. Since a death mage might be feared or shunned, the story could explore how they form relationships or deal with being alone. And there's likely a theme of discovery too. Discovering new forms of magic, new places, or even new aspects of themselves as they progress through their adventures as a death mage.
I'm not sure specifically as I haven't read the exact 'death mage light novel'. But usually, the main character would be the death mage himself. There might also be a mentor figure who teaches him about his powers at the start, or a sidekick who helps him in his adventures.
In 'death mage novel', there are several prevalent themes. Firstly, the exploration of mortality and immortality is quite common. The death mage may be in a unique position to either manipulate death or have some form of extended lifespan, which leads to questions about the value of life. Secondly, there is often a theme of redemption. Even though death magic is associated with darkness, the protagonist may strive to use it in a way that redeems themselves or others. Additionally, the theme of power and its corrupting influence is present. As the death mage gains more power over death, they may face the temptation to abuse it.
One of the main themes is self - improvement. The weakest mage has to constantly strive to get better. Another theme is friendship, as he meets various characters who help him along the way.
Well, a 'death mage light novel' would typically tell a story about a death mage. In many such novels, the death mage is often an outcast because of the nature of their magic. The story could involve his adventures, like exploring ancient tombs filled with dark magic or facing off against powerful enemies who fear his abilities. There might also be a backstory about how he became a death mage, whether it was through a curse, a choice, or some other means. And of course, there would probably be other characters, some who are allies and some who are foes, all interacting in a richly detailed fantasy world.
One of the main themes is the battle between good and evil. Light, with the Death Note, represents a form of extreme justice that blurs the line between right and wrong.

The use of the Death Note to kill people, even criminals, raises questions about who has the right to judge and take lives.

As the combat mage embarks on their adventures, they might form alliances and develop deep relationships with other characters. Additionally, the exploration of different magical realms or the discovery of new magic spells could also be important themes.
Isolation. Since death magic is usually seen as something dark and taboo, death mages are often ostracized from society. They may live alone or in small groups of outcasts. This isolation can also lead to further psychological changes in the character.
