Tasha Godspell is a Black Class WH, achieved after only one year of training under his master. His goal is to rescue his sister Aria from the North Witch's influence, and have her remove the curse on him which will eventually kill him, and take her back home to their mother. In general he is obsessed with money, and a swindler, but he is very kind to women and witches, claiming he'll never kill a witch, but take her hat to make her powerless. He was trained in using a Magic Bullet Gun by his Master, the White Witch Edea Florence, whom he cares very much for, and does not hesitate to attack anyone who may insult her name.
His Magic Bullet Gun can fire three types of ammunition: Piercing, Grenade, or Tranquilizer. His Arcane Desert Eagle Custom has the firing power of 10,000 bullets in a single shot. The recoil is so great it can break his arm after 3 shots, and heavily drains his mana. In addition to mana bullets, Tasha can also fit real bullets into his guns. His Dimensional Gallery stores his guns, supporter, and also regulates the flow of mana in his body. It is revealed later that he can convert into a S-level White Class using Dimensional Gallery's summoners to sing "The Songs of Moirae" to release his limiter, however his mental state is very unstable when he is at this level.
He received Halloween, a pumpkin doll supporter, from his teacher Edea, before she was killed by his sister. As such, he treasures Halloween above all else, but he does occasionally shoots it or mistreats it in a comical fashion. During the fight with Ryuhwan, Tasha broke one of Halloween's seals before Ryuhwan's Halloween could kill it, reverting his Halloween's shape back to its original form of a young girl, greatly surprising him. As a result, Halloween received an increase in her speed and strength with the release of the first seal, and it is hinted that she will be able to be even stronger with the second release. Tasha may or may not have feelings for Halloween, as his reaction to Cooga's taunts have shown.
It is revealed late into the series that Tasha is capable of generating his own mana, and is the only male shown to be naturally capable of doing so, as Merlin had to change himself into a woman in order to do so. His source had originally been dormant, but responded when he used The Song of Moirae, the mana awakening his source. It is unknown how powerful his mana is, but is implied to heavily surpass that of an S-Class witch, as Merlin mentioned Tasha's mana source far outclassed his, who's mana level is that of an Archmage. It is because of this that East and North are keeping a close eye on him.
His hobbies include cleaning, cooking, and counting money. His likes are traveling by himself, money, and free stuff, and he hates things that don't make money. He seems to attract girls who are shy or outgoing and he has a rivalry with fellow Witch Hunter Cooga.
