1) I forgot to add that Archer also has photos from the burned department store, of the shrine located in the basement. All of the photos - from the forest, including field shots of spell tags and straw dolls nailed to trees, as well as the sigils on which gods and shinki were imprisoned, and much clearer detailed photos of spell tags and dissection of the straw doll, and the photos of charms from the said department store and the shrine, are handed on disposable flash drive. There are also video clips.
Aside from the digital data Archer includes physical evidence - several spell tags from the forest, charms from the department store fire and a straw doll or two from the forest.

2) Okay, so to clarify things, the only spell tags and/or charms found in Mitsui's house are leftovers from the forest? And that there's no different ones present?
(to clarify things further - Archer was supposed to be shadowing Mitsui during his meet with Zelda, Shun and Hibiki. I talked to Jamie about throwing him into the log but couldn't due to the lack of time. Can I assume that after shadowing Zelda after that meet Archer did find a charm hidden somewhere in Tokyo Daijingu, or was he unable to? In case he did, what are the specifics of the charm itself?)

3) Regarding Mitsui's laptop Ginia's going to copy the hard disk to break into. How much time it will take depends on if it's an easy password she can social engineer or a much more secure one. What will she find there?
