After getting out of the tomb, Ishizu almost absolutely dedicates her life to cataloging and recording everything left in the tomb. It’s how she gets her job in the museum, by offering them the once in a lifetime insight that she and the Ishtars alone have. It’s partly to survive after daddy Ishtar’s death, partly because she has seen that it will help her get back to Marik, and partly out of guilt, for everything that she couldn’t stop from happening. Her job gives her an almost neverending to-do list, keeping her busy in an escape from her guilt. Some of these include translating the books and scrolls of her father’s library, and cataloging the artifacts she from the tombs.
