Garden Takamineke no Nirinka (Japanese: ガーデン 高峰の 虹色) is a six‑episode original net animation (ONA) produced by the independent studio and released in early 2024 on a streaming platform exclusive to Japan, with an English subtitled version arriving worldwide a few months later. The title can be loosely rendered as “The Rainbow Garden of Takamine” , referencing the mythic garden that lies at the heart of the series’ world‑building.

There are no official mainstream streaming offers (like Crunchyroll or Netflix) for this specific title due to its explicit content.

Garden Takamineke no Nirinka follows the quiet, magical world of a secluded garden where the line between the ordinary and the fantastical blurs. The story centers on , a young caretaker who discovers an ancient, sentient tree— Nirinka —that holds the memories of the garden’s centuries‑long history.
