Ii Style Leg Strikes is a martial art exclusive to Naotora Ii. It seems mostly comprised of powerful and multi-level kicking attacks that both do impressive damage, and have easy-to-perform commands from attack strings. Despite the name, some of her other moves involve use of her hands (in punches, or slaps), and her buttocks (including a butt-first leaping tackle, a move where she falls onto a downed enemy with her butt, and some moves in which she crushes an enemy under her butt).
Some of the moves appear to have magical properties as well. For example, Naotora's Yamabuki (山吹, lit. "Mountain Blast") and Yuzuruha (弓絃葉, lit. "Bowstring Leaf") strikes produce a small cyclone that lifts the opponent upward, her Sakura-Bana (桜花, lit. "Cherry-blossom"), Tama-Bahaki (玉掃, lit. "Jade Sweep"), and Murasaki (紫草, Murasaki-gusa, lit. "Purple Herb") strikes create sakura petals (her Sakura-Bana also ends with her shooting a magical pink torrent of energy at her opponent), her Ii Family Creed (井伊家家訓！, Ii-ke kakun!) stance produces what appears to be a wind-like aura, and her Musou Attack (無双奥義, Musō Ōgi) Power Blow has her shoot crescent-shaped energy bolts while simultaneously striking her opponent with kicks.

- Save for some of her attacks, Naotora's fighting style emphasizes use of the lower body (her legs and buttocks).
- Many of her attacks have originated from Samurai Warriors 4.
- However, the moves she uses that utilize her buttocks were never used at all in the Samurai Warriors series.
