This work is a notable piece that closely follows Rin-chan as she attempts her first experience with internal release. Rin-chan's tension and anticipation are vividly conveyed, making her initial experience a must-see. However, viewer opinions vary; while some expect more hardcore elements, others feel that the slow pace leaves something to be desired. We hope for further growth from the lead, Rin-chan, and are keen to see what evolution she will showcase next. The future developments are certainly worth watching!
