Permanent Corpse - I want to reanimate

Japanese: 永久死体 - えいきゅうしたい

...These corpse phenomena are accelerated in summer and delayed in winter.
[Abnormal Corpse Phenomenon]
Abnormal corpse phenomena occur when a corpse is placed in a special environment, and the normal decomposition process does not occur or stops midway, and the corpse remains in the state it was in at the time of death for a long period of time. These phenomena are called permanent corpses. These include mummies that are created by drying, rotten cheese-like or gypsum-like corpses that are created in moist, air-tight environments, and the third type of permanent corpse, which is neither a mummy nor a permanent corpse.

From "Dead Wax"

…It is rare for the whole body to become completely necrotic, and the hands and feet are often skeletal, with wax clumps still attached to the bones. Once necrotic, the body retains its original shape for a long time, so it is called a tenable corpse, along with a mummified body. Sometimes traces of a rope or various injuries remain clearly visible, which can provide important clues about the cause of death, whether it was suicide or murder, etc. …

From [Mummy]

…a tenable corpse. A corpse that has remained almost intact for a long period of time in a dry state. In ancient times, it was also created artificially.

【死蠟】より

…全身が完全な形で死蠟化することはまれであり，手や足は白骨化していることが多く，骨に死蠟塊が付着した状態のものが多い。死蠟化すると，長期間にわたり原形が保たれるため，ミイラとともに永久死体tenable corpseといわれる。索痕や各種の外傷が明りょうに残っていることがあり，死因や自他殺などの重要な手がかりを与えてくれることがある。…
