Who can beat Shiba Tatsuya?

Just finished reading Mahouka and I gotta say, the main character is a beast.

This guy:

Tatsuya is at full power. He's severely restricted out of his abilities most of the time cuz of how highly dangerous they are, the military labeled Tatsuya's magic as classified.

Location: Open plain in Japan


Tatsuya's abilities:
-Decomposition/Mist Dispersion: The ability to decompose anything he chooses to subatomic particles.
-Regrowth: The ability to restore objects, be it living or non-living things. To be precise, he backtracked through the 'history' of the target and obtained the instant before the object suffers damage, then he rewrites the object's information structure (in other words, he made it so the damage never exist in the first place).
-Automatic Restoration Ability: Same as Regrowth but this is an automatic ability that activates whenever Tatsuya himself received anything that could lessened his ability in combat (injury, losing consciousness, etc).
-Elemental Sight: The ability to link to the Information Dimension (the dimension where information structure of everything that exists and has a physical body are recorded). He can expand his vision, detects someone's presence even when they're trying to hide it and read the information of every existing data.
-Third Eye: Using this, Tatsuya can link himself with a platform equipped with cameras to watch the national border that was in the stratosphere over Japan. Meaning he can target his enemy beyond kilometers of range.
-Material Burst: Tatsuya can convert mass into energy using Einstein formula (e=mc²), he converts 50 milligrams of water (a drop of water) into 1000 tons of TNT. The highest he accomplished was converting 1 kg matter into 20,000,000 tons of TNT (20 megatons). He can also selectively chooses the thing he wishes to convert.

Pic:

-Gram Demolition: Cannon Ball of psions (mana in Mahouka) that demolishes any records of magic (dispelling magic).
-Flight: Self-explanatory.

There are more but I forgot about the details.

And also, no insane guys who can destroy galaxies by a gesture or other who are stronger, etc please. This is for strongest earth character only.

Doraemon.. infinite possibilities BTW =D

lol maybe xD, his gadgets got some crazy stuffs.
But he had problems searching for them and Tatsuya only need a gesture to decompose him.
