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?!
The members of Bal Masque have left the city after their last clash with the Flame Hazes, and as a result the Flame Hazes and their allies have been living a peaceful life; that is, until Yuuji and Shana encounter a Tomagura with the ability to create imaginary worlds from dreams. During a fight against it they learn that Yuuji has a Keeper within him protecting the artifact that grants him life: Reiji Maigo. Meanwhile, in school, new and suspicious students and the interest of fellow classmates have made Shana and Yoshida’s relationship even more complicated. With girl troubles at every turn, Yuuji must continue his training so that he may protect Reiji Maigo from the hands of Bal Masque.
In both animes there exists a very strong desire to protect, and not just one person, but everyone. The only difference is that Kazuki protects right from the start whereas in Shana, Yugi doesn't do much until right near the end. However, by the end of the animes both protagonists are clear what their goals are and have the determination to carry it out.
In a bizarre fantasy world, students known as meisters are trained at the illustrious Shinigami Weapon Meister University; but the tools they wield are no ordinary weapons! Each meister is paired with a human-like being who can transform into a weapon at will; and after defeating a pre-kishin - a human whose soul has darkened - the weapon eats the soul within it. A meister's ultimate goal is to collect ninety-nine pre-kishin souls and one of a witch so that his or her partner will become an all-powerful Death Scythe. Maka and her partner Soul Eater; Assassin Black Star and his partner Demon Blade Tsubaki; and Shinigami's son Death the Kid and his partners the Demon Twin Pistol Thompson Sisters each vie for their ultimate goal, but plenty of challenges and adventures lie in their way!
Both Busou Renkin and Soul Eater are battle series with magical/enchanted style weapons and superpowered enemies. Busou Renkin has the alchemic warriors using their Busou Renkins to fight off the homonculous, and Soul Eater has Meisters and Weapons fighting together to defeat the evil Kiishin souls and witches. Both series have a lot of action, with some comedy mixed in for good measure. And as a minor correlation, both series involve a school setting. Busou Renkin has Kazuki Muto and Tokiko Tsumura spening a good portion of their time at the local high school, while Soul Eater has it's cast spending a large amount of time at the Death Weapon Meister Academy (or DWMA) where Meisters and Weapons study and train hard to fight Kiishin souls, Witches, and ultimately for Meisters to turn their Weapon partner into a powerful weapon. I have a strong feeling that if you liked one, you'll like the other.
Yusuke Urameshi was a normal middle school punk until he was hit and killed by a car, while saving a child. His selfless action earned him the right to gain his life back and serve as a detective of the spirit world, keeping the world of the living safe from a myriad of demons.

Can Yusuke protect the human and spirit worlds and still manage to save himself in the process?
Michiru has an unusual ability: she can see a dark ring around a person's neck that signifies their time to die. However, she suppressed her powers once she "saw" the deaths of her parents – until now. After accidentally seeing rings around the necks of two boys in her school, it seems that Michiru's powers are back for good. The two are zombies who are working for the secret loan office known as Zombie-Loan, and they need Michiru's help to find other zombies – those with dark black rings around their necks. Though Michiru initially refuses, due to a series of events it seems she has no choice but to comply...
Busou Renkin and Zombie Loan are not the same in the way of one action series is like the other. Rather these two have a great deal in common throughout their underlying characteristics. The characters in both series are all about determination. You need a lot of willpower to save the world, and you need a lot of willpower to save yourself. Different goals, but the same work ethic is required. These shows share that sort of effort, suffer a bit, and achieve some goal on the way to the end. There is also a shared quirky sense of (dare I call it) humor. Weirdness and bizarre twists abound. One episode of each is enough to see some of the "must have been smoking crack" plot management as well.
