- Name: Scarlet Secret Technique: Spikes of Airavata (緋色の秘密のテクニックスパイクアイラーヴァタの, Shinku Higi: Kasui no Airavata)
- Type: Scarlet Secret Techniques; Kyūseijutsu; Offensive; Supportive
- Rank: A
- User: Seireitou Kawahiru
Named after the white elephant who carries Lord Indra in Hinduism, this technique summons varied sizes of spikes from the ground or a source of earth, anywhere around Seireitou. However, these spikes are quite unique for the very reason that they are crystal. These spikes can also be summoned at any distance, close or far away from Seireitou. Also, these spikes can be morphed into clones. Unlike the Shadow Clone Technique, these clones are actual bodies, not not just copies that can poof away. These bodies can feel pain, bleed, and can think on their own. Seireitou's chakra is evenly distributed among every clone, giving each clone an equal fraction of the user's overall power. The clones are capable of performing jutsu on their own. They can also disperse on their own. The clones will be created in roughly the same condition as the original.
A characteristic that is unique to the Clones created by this technique, not counting the actual Shadow Clone Technique, is that any experience the clones gain during their existence is transferred to Seireitou once they are dispersed. This makes the technique ideal for spying, since Seireitou can simply summon a spike to the target's location and morph it into a clone to spy on that target, then have the clone disperse itself without returning to pass the information back to Seireitou. Any extra chakra the clone has when it disperses is also returned to the original. These clones can only be dispersed if either they "die" or are hit with a certain amount of chakra at a certain spot on their bodies, that vary with every clone.
These spikes seem to also be able to crystallize any substance, thus, Earth, Water, and Wood Release techniques are useless against it. Using these spikes, Seireitou can crystallize any physical material that lands upon the spot in which the spike is formed from. Meaning, this technique can also be used as a trap jutsu, along with it's initial offensive nature.
- This technique's trapping nature was based on Sode no Shirayuki's Some no Mai technique, used by Rukia Kuchiki, and shown in Bleach.
