Great Harem Technique

Konohamaru clones himself and holds his opponent in place. He then transform himself and his clones into bikini-clad females who swarm his opponent. While the opponent is distracted, Konohamaru and a clone ram them with a Rasengan.

Trivia

 * When used against Iruka, instead of ramming him with a Rasengan, Konohamaru approaches Iruka and pucks his lips, causing the latter to have a massive nosebleed that sends him flying.
