Trash II

Trash II is the nickname given by Naofumi to one of the residents of Glass' World.

Naofumi had many, unfortunate incidents that prevented him from learning his name, so he called him Trash II. In the anime, his name is revealed to be Kazuki.

Appearance
He wore a samurai-like armor over what appears to be a school uniform. He had his hair pulled back into a ponytail.

Personality
He is in a constant, insatiable need for power and authority. He is a self-proclaimed genius, arrogant, and boastful about his accomplishment. He wants to be special and better than everyone else. His level was unknown, but he boasted it to be very high. At the very least, his good qualities are his kindness to his harem. He chases women all the time.

Magic
He was able to cast magic without any chant, but the drawback was that it was less potent than the cast with a chant. He is also able to use a wide variety of magical elements such as fire, water, wind, and light.
 * Fireball: It forms a giant ball of fire that can be hurled at the opponent.
 * Healing: It is magic that is able to heal minor injuries on the target.

Weapon Skills
He was a decent swordsman who specialized in a katana.

Background
He was an alchemist and always works on revolutionary inventions. He was mentioned to be a genius who made many remarkable inventions to stop the misery of the people. He always chased after the woman trying to meddle in their affairs. He was mentioned to have researched on homunculus.

Volume 8
He developed a way to duplicate the dragon hour glass teleportation power of the four holy heroes and celebrated his success in the country where Kizuna was imprisoned. He witnessed Kizuna's attempt to reach the dragon hourglass and tried to stop her but was interrupted by Naofumi. Naofumi surprised him with his tactics and managed to escape but not before enraging Trash #2 for his first defeat in his life.

Afterward, Trash #2 traveled to a neighboring country where the Vassal Katana was stuck, like the sword in the stone. Just before Trash #2 was able to publically attempt to take the Vassal Katana, it flew out of the stone into Raphtalia's hands. He started calling Raphtalia a thief and started chasing her along with Glass, L'Arc, and Therese. During the chase, they met up with Naofumi, Rishia, Filo, Raph-chan, and Kizuna who were tracking them. After everyone's reunion, Trash #2 attacks them with copies of the White Tiger Protective Beast. The battle went relatively quick with Trash #2 relying on the power of the White Tiger copies while his own attacks were basic and predictable. Unable to accept defeat despite being sliced up, Trash #2 stands up in defiance. Reluctantly, Raphtalia kills him to stop his rampages.

Volume 9
Naofumi hypothesizes that after Trash #2 was killed, the spirit women of his group chased his soul. When Naofumi and his group explore Kyo's laboratory, they find Trash #2 still dead but floating in a tank of liquid. It looked like Kyo used him for research since the tanks around him were filled with homunculi which looked like Trash #2. The homunculi then broke out of their tubes, turned into copies of the Protective Beasts, and then attacked Naofumi's group. All of the heroes worked together to destroy Trash #2 and the homunculi. The flames from Kyo's attacks on the heroes eventually burned away Trash #2's body.

After some investigation, it turns out that Naofumi's hypothesis about the spirit women was correct as they found the spirit women's bodies. Kyo had also fed Trash #2's soul to some Soul Devourers before using the body for his homunculi experiments.

Relationships

 * Heroes
 * Kyo Ethnina: There are many similarities between them that both of their comrades and Naofumi couldn't ignore. L'Arc, a good judge of character, described them to be two peas in a pod.
 * Naofumi Iwatani: Nafoumi immediately disliked him for he reminded him of Kyo.


 * Companions
 * Tsugumi: Tsugumi was with him, since her childhood and stood by his side even in his questionable deeds.
