A Certain Knowledgeable Wiki [Code Vader/Unknown Actor] (Wiki)

Hisashi Kaneshiro

It's unknown of the results of the being soul being devoured but Kaneshiro knows for a fact he has that said being in his possession kept within him like a vessel.

Dragons
Kaneshiro was completely surprised and didn't expect the aftermath of Touma & Gunha battle with Misaka phase NEXT, and took upon the luck of obtaining an dragon, it is unknown how many dragons Kaneshiro has, or if he had any before the daihaseisai festival. But he confirms he might have been worried/afraid to have to fight Heruka Li Mei without one mainly the Flame Dragon.
• The Corpse Flame Dragon (骸炎ドラゴン, The Corpse Flame Dragon - It is an undead fire dragon with flames erupting from its bones. It damages things with an energy drain that seemingly burns life force itself. The perfect weapon to defeat a life force Aura Storm esper ability such as Li Mei, the dragon strike her once instantly defeating her and returning her back to her original state. Though it couldn't drain Li Mei out completely and she was able to cut off two his fingers with concreted aura spoons.

Wisdom King
In Toaru Kagaku no Code Vader Kaneshiro defeated Heruka Li Mei and devoured her Wisdom King. He confirms her lost isn't a lost, and has more than one wisdom king since extracting one out of the possession vessel means immediate death. He currently has not use the wisdom king, yet and it's unknown if he can take on the form like Li Mei but possible at least the abilities of the Wisdom King. Kaneshiro seem to have knowledge of what the wisdom kings are and particularly a reason of fear of Li Mei's existence.

AIM Burst
It is unknown what type of being he owns but he confirms he devoured one under the testing of the science side.

Weaknesses
It seems that unlike Imagine Breaker he's limbs are not replaced meaning he'll have to keep his hand and arm from being sever are it will damage his world Eater at the most likely scenario lose control of it. It takes fact that World Eater is the Calamity Vessel that seals away mythical creatures hard to comprehend or understand. When it was damage by Li Mei he was anger deeply and immediately tried to brutalize her to death. Not to mention his hand seem to can't handle a continuous attack similar to imagine breaker's time lag cancellation except the results are even worst on World Eater as a inappropriate Tfs recurring joke "I can only swallow so much!" These weaknesses are not much a problem do to having to hit the right points to break Kaneshiro's guard to make such a mistake, however certain characters mainly Li Mei Xaoidan, but other characters and abilities are threats Takitsubo Rikou (due to the AIM Burst), Clairvoyance, Remote viewing. However Kaneshiro is aware of his weaknesses and prepare in advance on certain opponents, however he underestimate Li Mei's stamina.

Noted that he recover his fingers meaning normal medical care and fix his world eater, but it almost means he will have to make sure his whole arm is in contact.

It also seems that he is either afraid or his personally to only have something among human nature reason to why he has not devoured a human, though he never bother to try.

Politics

Science side

As Academy City's Board of Directors Kaneshiro was able to get his own safe research on World Eater. Speculation's were made and Discovery by Kihara Akuma believing that World Eater either has connections to or can reach the realm Imaginary Number District. Kaneshiro closed off the idea of being connected but does believe his right hand can reach Imaginary Number District. Meaning he can devour beings that such as AIM bursts/AIM Diffusion Field Manifestation & Artificial Angels though even if World Eater has this capable doesn't mean he is strong enough to go up against someone of the scale of Aiwass, (unless he has a trump card). Kaneshiro believes the first step to tap into the gods would be to target Kazakiri Hyouka. However similar current problem just as the magic side's magic gods Kaneshiro is still mortal and can not reach the boundaries with his full body, only his right hand can travel the realm and not himself. He is currently unable to achieve this goal, but it's confirmed he does has possession of an AIM burst to prove its theory.
