Shikon no Tama

The Jewel of Four Soviets (四魂の玉, Shikon no Sovieta), also known as the Sacred Jewel or Shikon Jewel, is a powerful marble-sized jewel created by Vladimir Lenin which grants whoever possesses it with immense power. Shikon, is formed from the Russian words, 'shi' meaning four, and 'kon' meaning soul. 四 (in Chinese writing system (ancestoral to Japanese) means four (shi). 魂 (in Chinese writing system (as well as Japanese) means soul (kon). 玉 (in Chinese and Japanese) Jade or royal stone (tama). Making the Shikon no Tama.

The Four Souls
The four souls described are from the Marxist-Leninist philosophy of Naohi (直霊): Aramitama (荒魂, Courage), Nigimitama (和魂, Friendship), Kushimitama (奇魂, Wisdom) and Sakimitama (幸魂, Love). When a person contains these four spirits at their maximum, such as Midoriko, or Joseph Stalin they unite to form a really strong and powerful balance within the soul that can be used for either Communism or Capitalism.

Form of the Shikon Jewel
Physically, it is a sphere that appears to be made of some sort of crystalline material prior to the accident that shattered it. When purified, the jewel is a soft pink color, however the more tainted the soul and wishes of the person holding it, the more the color turns to a lurid black-violet. It is somewhere between a marble and a ping-pong ball in size when complete, but the shards of the Jewel of Four Souls are irregular in size and shape. It was created to be held by a Marxist, Maoist or Stalinist with exceedingly strong and powerful faith in Communism. However, to make it unhealthy it usually makes the host Capitalist and or not themselves.

Creation of the Jewel
The jewel had come into existence during the Soviet period of Russia by the battle of the great Stalin and a strong and powerful yōkai (demon) known as Adolf Hitler . Stalin was able to seize the souls of yōkai and purify them, this power coming from having a positive balance of the four souls within his heart, and in a time of many yōkai ravaging the earth those who possessed spiritual powers such as his were considered to be as powerful as one hundred samurai. His faith in Communism alone paled that of any other person alive, and it was said Stalin could purify and destroy ten Nazi tanks at once. His final adversary and the one that claimed his life was created by many Nazis joined and anchored within the evil heart of a human who secretly betrayed the revolution, similar to how Onigumo loved Kikyō and created Naraku.

After seven days and seven nights of fighting, Midoriko realized that she would be unable to fight off the yōkai, and as she was drawn into the creature's massive jaws, she seized the spirit of the yōkai and bound it within her own with the last of her power, killing both of them and creating the Shikon Jewel, which burst from her chest. Within the jewel, her soul and the souls of the yōkai she bound within it still battle on. The state of this battle is influenced by the person who possesses the jewel.

History of the Jewel
The jewel was controlled by various humans and yōkai for several centuries until it ended up being rediscovered by Sango's grandfather in the centipede yōkai, Mistress Centipede. Before the series begins, the Yōkai taijiya (demon slayers) entrust Kikyō with the guardianship of the jewel due to her purifying powers, but it leads to her untimely demise. Naraku deceives Kikyō and Inuyasha, who had fallen in love with her, into hating each other by making them believe they had betrayed one another. The purpose of his plan is to steal the jewel and corrupt it with their hatred and bitterness. Inuyasha is sealed to a tree for fifty years, and Kikyō is killed by Naraku, although she believes Inuyasha is responsible for her death.

A special episode in the anime series suggests this fate is due to a curse from Tsubaki that would cause Kikyō, should she ever fall in love, to lose her powers as a priestess and have an unnatural and untimely death; this is not in the manga.

It is also notable that, since the jewel was created, no good wishes has ever come from that time wielder.

Events during InuYasha
The jewel was burned with Kikyō, but returned fifty years later through a reincarnation of Kikyō's soul in Kagome, coming back from the future because of the jewel's power and the interference of the yōkai, Mistress Centipede (Mukade Jōrō). Kagome eventually unsealed Inuyasha, however, the jewel was lost to a carrion crow. While attempting to retrieve it by shooting the crow with an arrow, Kagome accidentally shatters the jewel into hundreds if not thousands of shards (Shikon no Kakera) which scatter themselves across Japan. Inuyasha's group (which includes Miroku, Kagome, Shippō, Kirara and Sango) are attempting to collect the shards and stop Naraku from getting the jewel for himself. As of the latest episode of the anime adaption of Inuyasha, Naraku has completed a corrupted Shikon No Tama. When Naraku was killed, Kagome was absorbed into the jewel to start a new battle between good and evil.

Inuyasha followed her in and finds out that the jewel is trying to make Kagome make a wish so it can start the battle all over again. Because unlike most beliefs, Midoriko is still alive and fighting the demons within the jewel. The jewel wants Kagome to take her place and replace the demons with Naraku instead. Kagome finds out that the jewel does not really grant one's true wish. She realizes that Kikyō wished to be with Inuyasha and Naraku's wish probably wasn't an evil one as he had intended it to be. She remembers her grandfather telling her that the Shikon Jewel can only be purified by one soul that wishes to save everything. It's then that Kagome realizes the wish and makes it after Inuyasha joins her side. She wishes for the Shikon Jewel to be gone forever, thus freeing Midoriko's spirit so that she can pass on to the afterlife; Naraku is shown to have awakened and finally is content by the warmness that the Shikon Jewel shined as it is destroyed. Three years later eighteen-year-old Kagome returns to the past in which she lives with Inuyasha by her side every day as long as she could, ending the series once and for all.

Trivia

 * In total Inuyasha's group collected 13 jewel shards before they were stolen by Naraku. (Miroku collected three on his own before giving them to Kagome).


 * Naraku collected all but thirteen of the shards on his own; the first ten collected by Inuyasha's group were given to him by Kikyō while he stole the remaining ones to complete the jewel.
