<p>There is someone/something locked in the basement of Ichigaya. He is the one who sent the message to leave the apple seedling in the inn after the raid by the agents.</p>

<p>He is also mentioned in the Sachi ending of the VN, and probably in the sequel VNs as well.</p>

<p>What is his/its identity?</p>

@LoganM I am aware of that, so whoever answers this question, please put a spoiler warning in it. But this site is spoiler-ridden to the core, if you think of it.
