Tsubasa: RESERVoir CHRoNiCLE, Rave Recommendations
A girl who lost her memory, a lot of kinda weird guys that travel around worlds. They have rare pets that can talk and be so useful.
Both mangas have similiar elements, while the enviroment is different. They have the main character and heroine both working together, while they travel, find friends and comrades and fall in love. Tsubasa RESERVoir CHRoNiCLE has a lot more serious atmosthere while Groove Adventure Rave is more goody and funny, but both main characters are focused to their goals while protecting the ones they love
