Withering moon lit rose

Ryuunosuke Akutagawa was spending the early evening with his sister Gin in their shared apartment. Ryuunosuke was slowly nursing a cup of fig tea, while Gin had almost finished her milk tea. "Shouldn't you be heading to sleep, you're being dispatched in the morning, correct?"
Gin nodded in agreement and quickly downed the remains of her tea, before heading off towards her room.
His thoughts were interrupted by an obnoxious knocking upon the door. Ryuunosuke rose from the kitchen table and swiftly made his way there, the now more rapid knocking did not improve his now foul mood. He was expecting to see some neighbour or child making this racket in the middle of the night, the neighbours always did like to check in on the twins which was troublesome at times, Ryuunosuke swiftly opened the door to be met by someone he didn't expect.
"Jinko?"
