Note: The phrase appears to be Japanese romanization with possible minor misspellings. I assume the intended phrase is 「親戚の子とを泊まりだから」 or more likely 「親戚の子を泊めるだから」, but the most coherent interpretation for an animation context is the line or concept "親戚（しんせき）の子を泊めるだから" — meaning "because I'm hosting a relative's child (overnight)" — or it could be a song/line quoted in an anime. Below I treat this as a short Japanese phrase used in an animation (voice line/scene) and explain how to analyze, localize, and link it to animation assets and distribution. If you meant a different exact phrase or a specific anime, tell me and I will adapt.
