I am from India, this anime or animated series (I can't remember this was made by the Japan or other countries) was aired between 2009 and 2012 probably in Jetix/Disney XD (but I'm not sure).
This anime starts with a boy (the main character, I forgot his name) who find a stone (or crystal like thing) in his dad's property, his dad was missing that time. Some day he accidentally hire a creature/monster from that stone. Other day some creature attack him and he was saved by his creature and the story begins.
In his journey to solve the mystery he meets a middle aged man 'Dante' (probably that was the name; this is the only character name I can remember). He had also some stone. After that they meet with one girl and a women (one of the girls is same age with the main boy character and probably will become his partner as the story goes on). Another women probably Dante's partner.
Four of them started their journey to collect all the stone/crystal. They are collecting twelve legendary creatures to defend against their enemy. I watched till they collect 4 legendary creatures' stones. This anime is kind of touch with archeological things.
This story kind of matches with 'Kiba' anime series. This animation series name probably between 5 to 6 letters. That galactic football was also hiring besides this anime series.
