Storm Release Secret Technique: Demon Dragon Storm

This technique uses the Storm Release Kekkei Genkai to produce a massive thunder cloud that can infinitely absorb chakra to grow in size and strength. The amount of chakra it receives will also increase. The user can apparently channel this absorbed energy into the earth, meaning it will lead to a bigger technique.

By using different seals while active, It can summon multiple red pillars of chakra in the area and/or mass-absorb multiple jutsu through a suction into his mouth.

Trivia

 * When written as '乱気流', rankiryū means 'turbulence'.
 * After Hiruko uses this technique, and the focus changes back to him from Shikamaru, his last seal changes from Tiger to Bird, which is likely a mistake as it is the same seal Shikamaru is holding at that time for his Shadow Sewing Technique. When he reactivates the technique to absorb Naruto's Big Ball Rasengan, he uses the Horse seal instead.
