Natural Genius and Hourai Pharmacist
The personal recollections of Eirin Yagokoro.
Deliberately fashioned to suit her aesthetics, the red-and-blue covered volume is emblazoned with a silvered cross seated upon a larger, sunken lemniscate; this central sigil is flanked by a pair of constellations arranged in a trigonal planar bent conformation - the very same hallmark that is seated upon her head. "Eirin Yagokoro, M.L." is scribed across the face of the volume in plain text, leaving little room to question the identity of its possessor, in case the overall style left any doubt.
There is a locking mechanism of the same burnished silver color located at the side. It is of (seemingly) ordinary construction, yet betrays no keyhole or any other mechanism by which the lock functions.
Truly, it is a journal as unique as its owner.
