I made this post just to announce that me and with my friend, Star Verenable, have updated the lorebooks for Umamusume, now also including OCs and Anime Characters. There's still alot of Anime Characters that we haven't included in the lorebooks yet and we'll add them in once i made a bot for them or have the time.

The lorebooks will be made public and if you need the json files, DM me on my discord account, piethorus.

Another thing, since Star Venerable got sent into the shadow realm by jai, i'll be posting some of his Umamusume bots (Sunday Silence, Halo, etc.) that got deleted alongside his account. With permission from him ofc).

If there's any of his other OCs bot that you guys like, ask in the comment and i'll post it.

That's all, thanks.

Update: The reason for why the Umamusume Characters 1 lorebook was glitched because of jai's size limit for lorebook. It's now fixed.

Update 3/8/2026: Me and Star Venerable have updated the Umamusume World lorebook, adding more informations about Umamusumes: their biologies, clothing, injuries, slangs, phones, roads, etc. We also updated URA, Unity Cup, Grand Live and added Grand Masters (we'll be adding more training scenarios in the future).

We have added an OC scenario being the Umalator (based on the VR Umalator Malfunction series by @kopperion). We made it to be a VR training scenario similar to the Grand Masters but more extreme and less lenient, also with the chance to malfunction (like the arts). The Three Goddesses for this scenario will be Eclipse, Matchem and Herod.
