Entering the Fire Element form was unconditional for me.
Not only was it unnecessary to summon a fireball with my right hand to ignite myself, but the condition of "igniting myself" itself was also unnecessary. Since my body was composed of flames from the start, I was already burning. Whether to enter the Fire Element form was entirely up to my thoughts in a moment.
As expected, the Weirdo Maker most likely intended to use the black mist to teleport us to the Human Bureau's stronghold, or some other place that could "deal with" us. If it were just me here, I would have been happy to indulge him and see what the destination had in store. However, since there were two other people here, it was necessary to prioritize safety.
As the Fire Sea engulfed the entire street, the black mist blanketing this area, potent enough to make ordinary people lose consciousness, was all destroyed.
