Summoning: Rashōmon

Shut tightly, this menacing gate when summoned provides a tremendous defence for its summoner and is able to completely intercept an opponent's physical attack. According to Sakon and Ukon, this technique boasts an ultimate defence and the fact that Kiba Inuzuka and Akamaru managed to dent it was no small feat. He also claimed it was developed by Orochimaru; however, Hashirama Senju performed the summon decades before, bringing illegitimacy to his claims.

Trivia

 * This summoning appears to resemble a more demonic depiction of the main gate of old Kyōto.
 * This technique is used offensively in the video games, summoning the gate directly beneath the target.
