Death and reincarnation are inescapable, but what happens in between? Without warning and without his memories, a boy who only recalls his last name - Otonashi - wakes up next to a girl named Yuri who offers him a gun and tells him to shoot an angel. Assuming it must be a misunderstanding, Otonashi is then almost killed by the angel and is drawn into Yuri's army to battle to delay the beginning of his next life. Immortality is within reach, but if Otonashi remembers how he died, will he keep fighting or allow himself to vanish?
Akari has always known two things: she’s a skilled fortune teller, and she has an uncanny knack for growing huge, healthy plants. But after experiencing a traumatic tragedy the girl soon discovers the true horror of the world: there exist evil spirits known as Daemonia that infect people’s hearts and grant their hosts wishes in exchange for a contract. After the wish is fulfilled, the human is turned into a murderous monster, and only Sephiro Fiore, a group of girls who wield the powers of the Elemental Tarot, can put a stop to them. As the bearer of the Sun card, Akari must join Sephiro Fiore and help take down those possessed by Daemonia, no matter the cost.
If you like watching people transform and use spritual weapons to kill "undead" monsters, both of these are quite similar (at least for the first little while of Bleach). When killing Hollows is still a major part in Bleach it's exactly the same situation as the Daemonia in DBI. A person is turned into said monster and can never be returned to normal, both series' having the issues of having to kill people they love after being turned into their respective monster.
In 2010, the Britannian Empire enslaved Japan using powerful mecha known as Knightmares; in the aftermath Japan was renamed Area 11, and its people began a hard and terrible existence.

One day, in the middle of a terrorist attack, Lelouch meets a mysterious girl who grants him the ability to control minds. Can he use his new power to fight for freedom, or will his hatred twist his good intentions into mindless acts of vengeance?
In a world where supernatural beings known as youmu are hunted by Spirit World Warriors, Akihito lives an eventful life. He’s a half-breed from a human mother and a youmu father, and is immortal - a fact that saves his life on a regular basis, for his bespectacled classmate Mirai can’t seem to stop stabbing him in the chest. She’s a Spirit World Warrior with the power to control her blood, which she manifests into a sword; and with low self esteem about her abilities to hunt youmu, Mirai constantly uses Akihito as target practice. In hopes of being left alone, Akihito must now help Mirai gain confidence to take down sinister youmu.
These are both anime about high schools students with special powers fighting supernatural creatures to protect their town. Both these shows mix school life, some comedy with a lot of action.
Bleach is a lot longer than Beyond the Boundary and involves going to the spirit world for long stretches. However, these are both anime where those with powers fighting to protect what is important to them. Beyond the Boundary has much higher quality art and animation. I also doubt it will take a nose dive in quality like Bleach.
I hesitate to recommend this one both ways but I will do so with a warning. Bleach really goes downhill after the first 63 episodes to the point where it's only worth watching for the most dedicated fans.
