Kekkei Genkai: Mangekyou Sharingan
Classification: Sword/ Genjutsu
Nature of Attack
The Totsuka Blade is a spiritual weapon, unique to Itachi Uchiha (read below for further information). It seals anything it pierces in a genjutsu like realm. It is concidered to be an extension of Susano'o, because Orochimaru searched but could not find it.
Kurisu's Totsuka Blade
Kurisu Taizen, who possesses the Mangekyou Omoigan managed to obtain the Totsuka Blade. He used Summoning Jutsu: Reanimation, and obtained it after defeating a resummoned Itachi. Itachi warned him of the dangers of the Blade. It should be noted he has the abilitiy to dispell the genjutsu as well. Kurisu himself admitted he only uses it when things get tricky, for he has already lost part of his sight. He uses the eight tails chakra to compensate.
