Doncs sembla que tens raó amb el que insereix el record d'ell mateix en el passat de les víctimes... Bé, esper una explicació més detallada en el proper capítol, així sí que sembla que s'ha patillat un poc...
Insert Presence: Book of the End has the ability to split the past of whomever it cuts. This ability works not by manipulating time and memories, but by literally inserting Tsukishima's presence into the victim’s history. Victims of this power recognize Tsukishima as someone closely connected to their personal lives, whether it is as family, friend, or lover.[64] He can even usurp the roles of other individuals in the victims’ histories.[65] Likewise, Tsukishima gains comprehensive knowledge of his victims’ memories. This power takes hold regardless of whether the victim trusted Tsukishima before being cut. Tsukishima can continue to modify his victims’ histories even after cutting them; however, if they realize that their altered pasts are inconsistent with reality, they are put at risk of mental breakdown.[15] By cutting an affected individual again, Book of the End’s effect on that person is dispelled.[66] Book of the End’s power also works on inanimate objects. For example, by cutting the ground, he can modify its history to alter its structure and set traps there as though he had done so long ago. By cutting a person’s weapon, he can gain complete knowledge of its techniques, including their weaknesses.[67] As with all Fullbrings, if Tsukishima dies, all traces of his ability vanish, returning his victims to normal.[68] (Unnamed)
