Shiki

シキ

Shiki in the Manga
Shiki was a member of the Tao clan, whose ancestors survived the war against Chronos 25 years ago (he confesses to Train during their battle that he would have participated in the war if he had been old enough). As a Master-Level Taoshi, Shiki manipulates his Chi (his own, even though his gender cannot be determined in the early volumes due to his attire; later in the story, he reveals his identity). Shiki's primary offensive method involves insect summoning, and consequently, his Tao Power is named "Insect". However, in addition to his insects, he masters the use of ink seals, employing them to manipulate his Ki in various ways, from creating a seal sword to generating an energy blast.
Shiki in the Anime
Shiki's backstory is not revealed in the anime. He neither fights Train nor plays a major role among the Apostles of The Stars, as he belongs to the elite team summoned by Mason to execute the Eden project, although he is frequently seen using his insects to gather information for Creed. He fights Anubis.
