On the eve of nobleman Oz Bezarius's fifteenth birthday, he and his loved ones gather to celebrate in a coming-of-age ceremony. But after Oz steps under a long-stopped clock and the hands finally move once more - thus fulfilling a mysterious prophecy - he is violently thrown into the legendary prison known as the Abyss by three cloaked intruders. Existing in another dimension, the Abyss is home to lifeforms born within its walls known as Chains; these beings can only live in the real world if they make contracts with humans, binding their power to the person's body. However, there's a catch - in time, the human will be overcome by the Chain's power and then thrown into the deepest level of the Abyss. When Oz wakes up in the Abyss he is quickly attacked by hungry Chains, only to be saved by one named Alice - a Chain who appeared just before he was thrown into the prison. Together, the two make a contract and return to the real world, where they are enlisted into the Pandora organization - a group researching both the Abyss and the trio that threw Oz into it. Along with members of Pandora, the duo searches to find Alice's lost memory fragments that are scattered throughout the world, to discover the secrets of the Abyss, and to determine if there's a way their contract can be broken without killing either Oz or Alice.
Mai Taniyama is a first year high school student who lives a carefree life telling ghost stories with her friends. One day, she meets Kazuya Shibuya, the head of Shibuya Psychic Research (SPR); and together, she tags along to help him investigate paranormal activities in a haunted school building. His assistant Lin was hurt during an incident to protect Mai from danger, so what more can Mai do than to take the job as Shibuya's assistant? Along with a team of other ghost hunters, they will uncover the mystery of a strange case coming their way, while Mai starts to discover her own abilities.
In the early 20th century, Kazuya transfers to a prestigious academy as part of an exchange program between Japan and Saubure, a small European country. But while Kazuya would love to make friends and have a typical school life, the boy is shunned by his ghost story-loving peers who believe that he's a "Black Reaper" to be feared. Things change one day when Kazuya wanders to the top of the library and discovers a lush botanical garden, and a beautiful, small, blonde-haired girl named Victorique who rarely leaves the building and is fascinated by unsolved mysteries. Together, the two develop a budding friendship and take on many chilling and dangerous cases that even the famous local detective Grevil can't solve.
Far, far away in a distant time, there is a tribe of people called the Golden Tribe who have the ability to create stars and foretell the future. They gave out a warning to those who have yet to mature: 'Move.'. Three tribes answered their call: the Silver Tribe, the Bronze Tribe, and the Heroic Tribe. Soon after, the Golden Tribe encountered a crashed ship in which only a baby human known as Age survived; they named the child's race the Iron Tribe and assigned one of the few living members of the Heroic Tribe to protect him and his race. Now, in a distant part of the galaxy, humanity is threatened with extinction at the hands of the other tribes. With only a prophecy to go on, they set out to the deepest depths of space to find their savior named Age -- humanity's last hope.
What Heroic Age and Pandora Hearts have in common are mature, responsible protagonists with a special and well designed universe. For Heroic Age, that universe is one filled with monsters with the power to destroy a world, inter-stellar warfare, and space opera drama in a grand SF adventure. For Pandora Hearts, the setting is Alice in Wonderland complete with a uniquely Japanese look at the matter, with a dual dimension setup to divide one world from the other.
For those that loved the deepness and character strength present in Oz Bezarius and the cast of Pandora Hearts, surely you will also come to appreciate the great design work on the cast of Heroic Age. It works the other way as well.
If you liked Horizon in the middle of Nowhere or Pandora Hearts then you would like the other.

They are good animes if you like the other. Watch them, and you'll know.
Ritsuka has nowhere to run or hide. He lost his memories and his mother’s loving support, and then his brother -- his sole defender -- was brutally murdered. He is entirely alone until Soubi appears, saying the words he most wants to hear, but refuses to believe: “I love you and will do anything for you.” Flung into a world of intrigue and magic, where bonded pairs battle and only Soubi can fight for him, he struggles to find his brother’s killer. Yet he must also face the most bitter question of all: if you can't remember who you were, does that mean you don't know who you are?
Pandora Hearts is a shounen whereas Loveless is shounen-ai, but if you like the idea of two people teaming up to fight magical/supernatural battles (where one of the characters is a tsundere), with a plot that's heavy with mystery of one, you're bound to like the other.
