You can watch The Tyrant Falls in Love (Koisuru Boukun) on a handful of free or niche anime/BL sites, but it’s not available on major streaming platforms like Netflix, Crunchyroll, or Hulu in most regions.

Quick options

Free anime / BL streaming sites

  • AnimeHub – Lists the series and offers free streaming of episodes (often with English subtitles).
  • Animefreak – Also hosts The Tyrant Falls in Love and lets you watch episodes online without required downloads.
  • Dailymotion – Has uploaded versions with English subtitles (quality and availability vary).

Dedicated BL / yaoi sites

  • OnlyHentaiStuff – Hosts the OVA episodes with English subtitles and, in some uploads, additional audio options (e.g., Russian).

These sites are generally “free” but may:

  • Show ads or pop-ups.
  • Have variable video quality.
  • Not be officially licensed in your region.

Make sure you’re comfortable with the site’s terms and any regional restrictions.

What the series is

The Tyrant Falls in Love is a two-episode OVA based on Takanaga Hinako’s yaoi manga Koisuru Boukun. It follows:

  • Morinaga Tetsuhiro , a gentle, gay research assistant who loves his homophobic, domineering senior, Souichi Tatsumi.
  • A controversial aphrodisiac incident that forces physical closeness and starts to shift Souichi’s attitude, leading to emotional tension and a slow-burn relationship dynamic.

The anime is officially rated TV-MA due to its explicit content.

Why it’s hard to find on major platforms

  • It’s a relatively niche BL OVA from 2010 with limited distribution.
  • Major services often avoid older, explicit yaoi/OVA content unless they have a specific BL-focused lineup.
  • Regional copyright rules can block some uploads (as seen on Bilibili, where it’s unavailable in certain areas).

TL;DR

  • Best current options: AnimeHub , Animefreak , Dailymotion , or OnlyHentaiStuff for free streaming with subtitles.
  • Not on mainstream platforms like Netflix/Crunchyroll/Hulu in most regions.
  • It’s a 2-episode, TV-MA yaoi OVA about a homophobic “tyrant” and his gay assistant falling into a complicated relationship.
