Romaji clan

The Romaji clan was possibly started before 3rd Shinobi War, when an average kunoichi of Hidden in Grass, gone to the Country of Swamp and got 'dropped' into hidden and old underground tunnel (it got collapse during the 3rd Shinobi War), caused by Iwa nins), came upon an out-of-place greenish-black scroll with mudded kanji for 'reptiles' being stuck in dried mud column that was formed long ago. The woman, Mouki struggled to pulled it out of mud column and after 13 seconds, the reptile scroll was out. Mouki jump out of underground tunnel and look for a shelter so she could examined the reptile scroll closely and to open it with caution (you never know that a scroll could be a boogey trap). Settling in no-named town, Mouki examined it and found what it seem a 'direction' that said 'in order to open this scroll, the Reptiles Summons Scroll, the would-be summoners must bring lizard, turtle, snake, salmander, and crocodilians, and mix all their blood along with your blood to make this scroll recognize you and your descandants a summoners for reptiles'.
