The Butterfly Hotel

Some doors only open once.
The envelope arrives without warning. Cream-yellow paper. A scarlet butterfly where a return address should be. Inside, a time and a place.
The hotel is beautiful. Five stars and impossible. A concierge with mismatched eyes welcomes each guest personally. His name is Hikaru. His voice is calm. His smile never reaches his eyes.
He has something for everyone.
An auction. A machine. A banquet. A fight. A mirror. A stage. A bed.
They accept. They always accept.
And somewhere behind the reception desk, the scarlet butterflies wait.
The Butterfly Hotel has many rooms. This is just the first.

For fans of Danganronpa and Death Parade.
