Some things in life are so bad that you'd like to pretend they're just a dream. Unfortunately for Kazuki, trying to save a strange girl from being brutally killed by monsters (and ending up dying instead) is an unfortunate reality. Out of pity, the girl replaces Kazuki's heart with an alchemy-based artifact known as Kakugane, so that he may live on. With this strange device, Kazuki gains the power of Busou Renkin -- Arms Alchemy; a power that will come in handy when monsters (and worse) begin to plague his town! Kazuki soon meets the girl from his “dream” (named Tokiko) in reality, and she tells Kazuki to get on with his life; but with his sister and friends in danger, that might not be possible. Besides, if Kazuki gives up the chance to show off just how manly he can be, how can he hope to win the heart of the alluring older-sister-like Tokiko?!
Both Busou Renkin and Rave Master has a boy and a girl as the main character. Both boys have magical powers to use their swords to fight for justice. The boys also fall in love with the girl during their journey
In times long past, the Shadow Lord was defeated by the Belt of Deltora, and its creator Adeen united the seven tribes into one kingdom called Deltora. The Shadow Lord bid his time, striking again generations later; he destroyed the belt and scattered the gems, thus leaving the land open to be easily subjugated. Now, in the present day, a young man named Lief does what he can to fight the forces of the Shadow Lord. On his 16th birthday, Lief's father confesses to being the last king of Deltora’s friend, and has reforged the sacred belt. With new hope, Lief takes it upon himself to find the gems, restore the belt, and to bring hope to the people of Deltora once more! Together with Barda, an ex-palace guard, Lief sets out on an adventure of a lifetime!
Deltora Quest and Groove Adventure Rave are both adventure series revolving around a young group of adventurers trying to regather the bits of a mystical item in order to defeat a great evil.

This powerful substance can be used as an anti-akuma weapon, and ultimately can help destroy the evil Millenium Earl.

Together with the Black Order, Allen must find all 109 pieces of innocence to protect the world and defeat Earl.
