Based on “shinseki no ko” (relative’s child) + “tomari” (staying over), this is almost certainly from the Japanese adult/controversial roleplay or drama genre known as “otaku content” where a cousin or relative’s child stays over — often ecchi or hentai-adjacent.
Common platforms:

No mainstream anime matches this exact title, so it’s likely doujin (indie) voice drama or a fan-made video.

The title, loosely translating to concepts surrounding "Because I’m Stopping" or "Because I’m Staying," acts as a thesis statement for the track. The song captures that specific moment of hesitation—standing on the precipice of change and deciding to hold on.

The lyrics delve into the feeling of being left behind while the world moves forward. Unlike high-energy breakup anthems, Tomaridakara is a slow burn. It speaks to the part of the listener that feels inadequate ("de nada" / useless / worth nothing) in the face of a fast-paced society.

Lyrical Themes:

| Category | Observation | |----------|-------------| | Accuracy | Overall faithful to the Japanese script. The majority of cultural references (e.g., obon festivals, kagami‑mochi) are retained, preserving context. | | Clarity | Font size and colour (white with a semi‑transparent black outline) are readable against most backgrounds. However, during a bright sunrise scene, the subtitles briefly blend into the sky; a slight background shadow would help. | | Timing | Generally synchronized, but there are a few instances (≈2 min 12 s – 2 min 18 s) where the English line lags by ~1.5 seconds, causing a brief disconnect between dialogue and lip‑movement. | | Cultural Localization | Most idioms are kept literal, which works for a film that leans heavily on Japanese folklore. One notable exception: the phrase “kaze no yō ni” (literally “like the wind”) is rendered as “as fast as a car,” which feels out of place. | | Spelling/Grammar | Minor typos (e.g., “deparment” instead of “department”) appear in a few subtitles during background chatter, but they do not affect comprehension. |

Bottom line: The subtitles are good enough for an English‑speaking audience, but a quick proof‑read pass would polish the experience.
