There were bloody bodies everywhere as a result of the Kyuubi no Yoko.
'Hold it off until Yondaime is here' yelled an injured Konoha Chunin.
'Why won't this beast die ' yelled another injured shinobi.
'You will all die at hands ha-ha. No one can defeat me because of my unlimited chakra. HAHAHAHA!!
Then all of a sudden a flash of yellow light appeared and a man was standing in the middle of the war torn battlefield. The man had a standard Konoha Jonin uniform with a white trench coat that had the kanji for Konoha's Yellow Flash.
'Alright the Yondaime is here now that demon won't stand a chance' yelled a dying Jonin.
' I should have came sooner. I just wish my little Naruto will understand what he will have to go to. I just hope he knows I will love him even in my death.' said the young Hokage.
Suddenly he did some complex hand sign and said Summoning Jutsu and a gigantic toad appeared. It jumped right in front of the beast and the Yondaime did the necessary hand seals and said Demon God Consuming Seal and sealed the beast into his only son Naruto Uzumaki.
FIN
Yo this is my first time I have tried to do this so I am going to do a simple one shot in how the Kyuubi was sealed. Bold means a summon or tailed beast is talking.
