Withv.tv

withv.tv (ウィズブイティービー) is a Japanese rental site that claims to be "the world's first service (probably) that allows you to rent reaction videos with full-length anime footage." The service heavily features reaction videos from Virtual YouTubers.

Overview
Due to Japan's stricter copyright laws in comparison to overseas countries, reaction videos and watchalong streams on sites like YouTube do not feature footage from the original show being watched. withv.tv works in partnership with anime rights holders and distributors to stream anime on their site and distribute profit from the rentals to them. The rental period for reaction videos with anime is 30 days. withv's anime and reaction videos are only available for a limited time.

withv.tv features reaction videos from Virtual YouTubers and talents from Yoshimoto Kogyo, known for representing popular "owarai" comedians. Some of the VTubers featured are already known for doing watchalong streams or reaction videos, like Luzyca and Jotei Setsuna. withv.tv also has the ability to get permission from the rights holders and distributors to let featured VTubers and Yoshimoto talents show their reactions with the anime video on their YouTube channels. Strict copyright enforcement on sites like YouTube don't always make this possible, as Asano Ruri's viewing of the first episode of Oddtaxi was blocked by YouTube in spite of withv.tv having permission.

The first episode of Oddtaxi is free to watch with your preferred VTuber or Yoshimoto talent, with the interface showing the anime video on the left and the reaction video in a smaller window on the right. When the anime video is played, the reaction video is synced with it automatically. The videos are available to watch from overseas, but feature no subtitles.
