Quadruple Giga

Quadruple Giga is Luka's most powerful skill. Dealing anywhere from 40,000-50,000 HP worth of damage, it is enough in order to finish off an opponent in one hit. The technique also only costs 1 SP, allowing it to be activated virtually at any time.

However, it has a numerous amount of drawbacks which makes the skill nearly unusable:

1. It takes four turns to prepare.

2. If Luka is hit during any of these four turns of which it takes to prepare Quadruple Giga, he will be cancelled out of the attack.

3. All four Spirits are deactivated upon use.

Due to these flaws, Luka can only use the attack against four enemies in Part 2 of Monster Girl Quest.

Imp: Imp does not know what's going on and thus can be attacked with Quadruple Giga when activated. If defeated with this technique, a defeat message saying "even her screams were sealed" will be shown across the screen. Using Quadruple Giga against Imp is overkill, and there for the sake of humor, as well as video game cruelty potential.

Tamamo: After using her Moonlight Cannon skill, Tamamo is exhausted and cannot continue the battle. Quadruple Giga can be used if you wish to at this point.

Granberia: She requests that you use this skill after the half way point of the battle is completed. She will wait for you to use the attack, and you will declare victory after this attack connects.

Alice: After Alice's HP hits zero and she requests you to kill her, you can use this attack to finish her off. This leads to a little extra dialogue which includes Alice lamenting over Black Alice's defeat by Heinrich.
