This technique covers the enemy's entire body with the kikaichū living inside the Aburame clan member's body. The chakra-sensing kikaichū spread over a wide range, and the moment they locate the enemy, the insects, following the user's orders, gather at once. The insects completely surround the target, making a globe. They restrain the enemy and start eating away at their chakra bit by bit. Before long, death will arrive. Even if the target manages to escape, the insects will immediately follow it.
In Naruto Shippūden: Ultimate Ninja Storm 2, this technique is instead used to send a big, slow moving sphere of insects towards the opponent.
