Story[]
The scene starts off with Tomoe Tachibana in Gabriel Cunningham's ward, writing a letter to her father. They converse a bit, with her then changing the subject on how ever since leaving her home she's strained herself, wanting to own up to her own strength, not her family's but then finishes off on how she realizes that "not everyone grows up all at once". Gabriel scoffs, stating the obvious, and adds in that if she's come to a realization then that proves that she's indeed grown. Gabriel then requests a coffee in which Tomoe jokingly states that replying on others is "not the path of honor", and how he should do what he can to help himself; seemingly ignoring her own past words on how one should not be straining themselves. She notes of Gabriel's seemingly broken arm in which she reaches out to touch it in which Gabriel yells out, stating that she should not touch him and how she's "doing so on purpose" as the scene then changes to Hanzou standing on top the roof's helipad, stating that it would be a while before she returns.
