Since I'm not familiar with this particular light novel, I can only make assumptions. Maybe it's about a young kendo practitioner who, through some special circumstances (could be related to the 'tensei' part), finds himself in a world where he has to compete in a 'colosseo' - like arena. And in the process, he attracts a group of female characters, thus forming a harem. There might be elements of character growth, intense kendo battles, and the exploration of different relationships within the harem.
I'm not entirely sure as I haven't read it in detail. But generally, it might be about a story in a world where kendo is important and there's a harem aspect involved, perhaps with the main character facing challenges in a colosseum - like setting.
I don't have specific information on the main characters as I haven't read the light novel. It could be a young male protagonist given the common tropes in harem - themed stories.
Online platforms are a great place to start. Amazon often has a wide range of light novels available. You could also check websites that focus on Japanese media and merchandise, like RightStufAnime. They might have the 'tensei kendo no harem colosseo light novel' in stock or be able to order it for you.
The appeal of 'isekai tensei harem novel' lies in the combination of two popular genres. The isekai aspect allows readers to escape into a different world, often filled with magic, adventure, and unknown. The harem part adds an element of romance and relationship dynamics. For example, in many such novels, the protagonist, who is usually a normal person reincarnated in a new world, gets to interact with multiple attractive characters of the opposite sex. This creates interesting storylines full of jealousy, friendship, and love triangles.
A few 'isekai tensei harem novel' titles are 'Sword Art Online'. In the ALO and other arcs, Kirito has interactions with multiple female characters that have some harem - like qualities. And 'Log Horizon' is also relevant. Shiroe, the main character, is in a world full of different races and characters, and he has relationships with several that can be seen in the context of a harem in the isekai setting.
Well, for one thing, the isekai tensei concept allows for a fresh start in a completely new and often fantastical setting. This gives the author a lot of room to create unique worlds, magic systems, and species. The harem part is appealing because it offers different types of relationships and character dynamics. Different characters in the harem can have their own personalities, backstories, and growth arcs. For example, in some novels, one girl might be the strong and silent type, while another is the bubbly and energetic one. The protagonist then has to navigate these different relationships, which adds depth and variety to the story. Also, it can appeal to different reader fantasies about love, friendship, and adventure all rolled into one.
Well, 'The Rising of the Shield Hero' can be considered. The protagonist is summoned to another world, which is a typical isekai tensei situation. And he has a group of female companions who support him in different ways, which gives it some harem - like vibes. Also, 'Konosuba: God's Blessing on This Wonderful World!' is very popular. The main character is sent to a fantasy world (isekai) and he has a group of girls around him, which is a classic harem setup in light novels.
