Solo Leveling includes references to other games and anime, such as Dungeon Defender and Ninja Garden. The author added a character from Dungeon Defender into the manhwa and included a character from Ninja Garden in chapter 68. Not just mangas and animes, Solo Leveling even has an easter egg of a character from a game called Dungeon Defender. Solo Leveling completely took this character from this game and added it to the manhwa. Not only that, but the author thought we wouldn't notice Ryu Hashibusha from Ninja Garden in chapter 68.
