Currently reading this. The beast wasn't the main point but it's a fun read if you like crazy characters. XD

Unfortunately I haven't been focusing much on action fantasy, so I can't particularly remember any manhwa with summon as the main focus except taming master but you probably already read it. (I did not like the Webtoon, but the novel is pretty good). You can find it on mangago too.
Also the rabbit wasn't a familiar but this Webtoon is one I like. I need to reread it because I forgot the story lmao, but I remember really liking it before hiatus
Sorry wasn't much of help. XD
Wait forgot the link. (Ps. I can't remember if he got any pets or summon. Totally forgotten the story)
