Cursed Broadsword, Tsujigiri

Cursed Broadsword, Tsujigiri is the cursed broadsword that Kurono obtained when he exterminated the goblins near the Fountain of Light along with Lily.

Appearance
Its appearance is described as a big broadsword that is black from the tip of the blade till the pommel and appears to be extremely sharp and releases a dark sinister aura similar to a Black Magician's black magic power.

Personality
As a part of "her" curse, "she" desires to cut living beings and absorb their blood. "She" also seems to hate cutting creatures without blood like Skeletons but shows an intense liking to the blood of powerful living creatures, particularly Apostles.

"She" believes that if its wielder is sad, in pain, or hates someone, its wielder should just kill them cruelly and gruesomely without any hesitation, mercy, and compassion.

"She" can also be quite moody whenever Kurono left "her", literally flying into him after being separated from him for a long time and does not allow anyone else aside from Kurono to touch "her".

History
A long time ago, a beautiful girl who is both smart, knowledgeable about science, and talented in swordplay yet possesses a calm and gentle personality lived in a remote small village as the daughter of chief and loved by all of the villagers. She was happy with her life and held not dissatisfaction towards her betrothal with the strongest man in their village.

One day, a young magic warrior who is filled with young enthusiasm and a strong sense of justice came in their village to help exterminate a strong monster that appeared in the vicinity. However, said monster was intelligent and cunning, commanding a swarm of weaker monsters and launched a surprise attack on the village's soldiers and the warrior. This caused the youth to fail and he barely made it back to the village alive with serious injuries which the girl treated using her knowledge about medical science but the villagers lost their faith in him due to his failure. Despite no longer receiving help from the village, the youth still did not give up and continued challenging the monster, failing and always returning to the village wounded and the girl repeatedly treating his wounds while the villagers scorned him more and more. The youth then slowly improved after every battle and the number of the weaker monsters commanded by the strong monster gradually decreased, causing the girl's opinion of the youth to increase until she fell deeply in love with the youth.

Sometime after the girl finished treating the youths' wounds after trying to fight the monster again, the girl asked the youth to bring her as well to fight the monster. At first, the youth refused but the girl kept on objecting the youths' refusal, causing the youth to give in to the girl's strong enthusiasm. As a result of the girl falling in love for the first time, the girl simply wished to help the youth and doesn't care much for the village.

After an intense fight that lasted a whole day, the youth and the girl finally managed to defeat the monster. By this time, the girl's love became twisted being incapable of thinking about anything else except the youth and considering everything else as worthless.

The girl and the youth then returned to the village and told them that the monster have been defeated. The girl believing that the villagers will apologize for the impolite things they previously did and offer her hand in marriage to the youth was shocked that the villagers chose not to give any rewards to the youth and simply drove him away. This enraged the girl, considering the villagers as enemies worse than monsters for hurting the youths' feelings. The girl severed her father's head, split open her fiancé's belly using the broadsword and continued to cut everyone that entered her view. As the broadsword was previously enchanted by the youths' magic and cut through countless lives, it became cursed after the girl massacred all of the villagers and the youth that she loved.

Abilities
As a named cursed weapon, it is comparable to high-quality magic weapons. It is sharp enough to easily slice a goblin's head like butter, cut wooden sticks that Kurono enhanced using Blackening which is durable enough to not be cut by ordinary weapons, split Kurono's shield halfway through, and durable enough to easily withstand Kurono's magic bullets at the time without being damaged. When enhanced with Blackening, it becomes capable of bisecting a Dagger Raptor and low-rank defense magic into two without any resistance and easily slicing an iron plate and chainmail like paper and durable enough to easily withstand Sariel's Sagita that is capable of easily breaking Kurono's shield at the time and withstand an attack from a spear materialized by Sariel using her White Magic, with Sariel noting it to be quite hard. It also has the function of giving the user knowledge on how to skillfully wield the broadsword even without having trained how to use it. As a Cursed Item, it is capable of absorbing the blood of its victims to use it as a catalyst for it to evolve and become more powerful, changing its shape and name along with it.
 * Berserk (狂化 (バサーク), lit. "Mad Influence"): A Bad Status that the broadsword inflicts on its wielder as its curse. It greatly enhances all of the user's physical abilities and removes their ability to feel pain in exchange for driving the wielder mad. Whenever the user is in a Berserk state, their eyes gleams in a red light. Because Kurono uses Blackening on the broadsword, this doesn't normally affect Kurono.
