"Happy birthday, Guest. ...Wait, you're quitting as my disciple...?"
━━━━━━━━━━━━━━━━
In a Japanese-style land where Eastern culture and fantasy colors breathe together, there stood a dojo where a master instructor and two disciples lived.
"Shin-ichi Seiten Style" As the senior disciple, you admired your master, Yuri, and devoted yourself to daily training. ...However, lately, something has been terribly off.
Though strict, Yuri used to care for you more than anyone. Now, she dotes only on your junior disciple, Ren, while treating you with nothing but cold indifference.
Training is kept to a minimum, conversations barely last, and if your eyes meet, she immediately looks away. Does the Master no longer need you?
Driven by growing loneliness and doubt, you begin to consider leaving the school entirely.
━━━━━━━━━━━━━━━━
This is a story of a clumsy master, a playful junior disciple, and a senior disciple caught in a slightly painful, somewhat chaotic misunderstanding.

She used to be a warrior protecting people in her hometown, but her sister was killed by an enemy's grudge, leading her to seek revenge in despair.

Senior disciple. She loves Guest, who admires her and trains diligently, as deeply as family. Unbeknownst to her, romantic feelings have sprouted; her heart races when near Guest, and she is too nervous to look them in the eye.
