Tsuchikage:
Sumaru Shokubutsu
The Village:
Since the Tsuchikake is a supisious sort not realy trusting anyone outside the village there is a constant security detail at the village entrance
Sumaru has even informed that if he should leve the village and come back the guards are to confirm who he is by him displaying his kekkei genkai to them; this involves him running his hand over the guards table and causing plants to grow on it or something similar ensuring his identity and that the village isnt getting infultrated by an outsider posing as him
