Shi ga kite iru
I think it is 死のグループ in Japanese.
"Shi" is how you say death in Japanese. "Shi" is also how you say four Japanese, which is a reason why 4 is considered unlucky in Japan as it is said the same way as "death" is.
Shi no engimono
shinigami. lol jigoku means place of death.
You may say 'shi.'
静かな死 (shizuka na shi) would mean "Silent Death" in Japanese.
There are no prevision, but I think that it's will be only in Japanese
Power of death = 死の力 Shi no chikara
