Intense experience! And suddenly Shiraishi has definite proof of Akiko being the real thing. Not that it's seemed to be much of an issue, but it can't hurt.

<i>Even cleaner than <b>the</b> had been when she put them on ...</i>

They?

<i>He told me that we <b>had</b> to purify the area</i>

"Have" seems more appropriate, since it's not something that they have already done.
