Reading Re:ゼロから始める異世界生活 in Japanese

Natsuki Subaru, a high-school student, is summoned to another world on his way back from a convenience store and finds that his only power is to return to an earlier point each time he dies. The narration follows his thoughts closely and is dense: literary words and four-character compounds sit beside his game and anime jargon, which makes it harder going than most isekai light novels.

How hard it is

Most of the book is narration, and the narration is where the difficulty lies. It reports Subaru's thoughts in long sentences full of written-style words (喧騒, 侮蔑, 渾身) and four-character compounds, then cuts to his dialogue, which is casual and full of references to games and anime. Furigana helps with the rarest words, but the narration needs a much wider vocabulary than the dialogue.
