Ar tonelico 2 OST - Indra (extended)

[juvemilano11]

i agree, one of my fav battle themes of the tonelico games

[lordyzonde]

This sounds almost like the Mana Khemia battle tune crystallized.

finally i found it geez xD. Best fighting theme imo. Makes you feel like you gotta give ur best and it slowly charges up just like how ur magic gets strongher by letting the girls singing till you finally release them on the enemy
