2 weeks after Kyubii Attack
Shinobi were still sorting through the wreckage of that horrifying night. After the Kyubii no Yoko was summoned, every able ninja threw every single kunai and shuriken in their arsenal. Many were hospitalized due to chakra exhaustion from using every jutsu they ever knew. There were several unseen and experimental jutsu and weapons used that night, no longer confidential. And yet, as soon as it started, it stopped. The sealing grounds used by the Fourth was considered Top Secret and only a few select shinobi were privy to the whereabouts of said grounds. Any "loose ends" were immediately mind wiped by Inoichi himself. Noriko had her hands full between selling flowers for the dead or missing and counseling shinobi who fought in the attack. She recruited several wives and former shinobi to tag team in these counseling sessions. Throughout all this, Ibiki and Anko were completely absent. No sign of where they went or where they were. Not even the best of message hawks could locate them, and they could deliver just about any message anywhere. Except, they dared not go to one place. Training Grounds 44 AKA The Forest of Death AKA Anko Mitarashi's backyard. She, Kushina, and Ibiki were known to spend entire weeks inside the Forest of Death on "survival trips". Most people believed that they were doing things other than just "training". In reality, they were doing things other than just training. One such thing was the ever cursed curse seal on Anko's shoulder. Their personal nickname for it was the pedo's hickey. Trying to remove it while keeping both Anko and the sealer alive was damn near impossible. Traps, suicide seals, explosive seals, summoning and even a "black hole" seal, the same one Danzo proposed should be placed on every shinobi and acadamy student; for "security purposes" he claimed. That idea was immediately rejected as Jiraiya found surveillance counterparts within the seal and even mind control and remote activation seals within said seals. Danzo claimed having no idea how they were included but earlier claims that he personally made said deal with only very minor consulting from other seal makers. It would not do good to see clam members being forced to reveal forbidden clan secrets nor for special shinobi to be controlled to such a degree that they wouldn't even be allowed to take a crap without being said so. The curse seal and Danzo's "security seal" were considered SSS ranked forbidden seals and the only punishment of placing those seals was immediate extermination of all involved, including the sealed. Anko was lucky for two reasons. One, she didn't draw any power from the seal, though it ruined her chakra coils down to the bare minimum of control. Oh, she could do the basic three and a few other low level jutsu, but any attempt of any jutsu above C class was considered "DO NOT USE UNLESS IN ABSOLUTE DEATH SITUATIONS." Fatal chakra exhaustion was a very real possibility for Anko and any attempts to regain said control were shot to hell. Before the seal was placed, Anko's chakra control nearly rivaled Tsunade's and possibly even exceeded hers. After, said control was genin's at worst and low chunin's at best. Hence a reason why she could never reach above Tokubetsu Jonin. One requirement was either creation of a jutsu or a new seal of sorts. Something considered extremely private and anything considered copying or replicating without said person's consent was considered abandonment of fellow shinobi, which carried the penalty of removal of shinobi corps, branding, for other villages to know that said person was removed from shinobi corps and why, and a minimum of 15 years in a maximum security prison along with every bit of chakra sealed except that for basic living. Life as a shinobi was considered no more than a far off dream afterwards.
Anko and Ibiki spent those two weeks alone burying Minato and Kushina at the base of the Tower in the Forest of death, where they were married, and morning the loss of good friends, lovers (Kushina and Anko had several Flings before and after Minato and Kushina dated and married. Minato was always invited to join and even suggested several hookups and sexual ideas, such as a chakra enhanced vibrator shoved up Kushina's twat while Anko bound her. Lets just say Anko and Kushina always enjoyed Minato's ideas, though they were few and far between [Minato had to somehow hide the fact he read Icha Icha novels and even was a part time consultant to Jiraiya].), and confidents.
