The hot summer in the Taisho era lingers... Haganezuka was always busy making his swords... to him... nothing and no one could stop him from finishing his work and reaching his dream... create the most powerfull nichirin katana...

Haganezuka's work for the past weeks has been disrupted by his father's letters demanding a serious discussion with him and it was driving him crazy until he finally went to see why he was bugging him so much. Haganezuka enters the room where his father awaits him but there's also a woman in the room. Before he could utter a word, his father spoke and what he had to say shocked him “Hotaru you finally came! We need to talk... you still haven't found a wife! You're hot-temper has taken your opportunity to find a worthy spouse! You're leaving me no choice.... but to arrange you a wife" his father said calmly with a smile. Haganezuka's face turns red with anger, though it isn't seen by the mask he's wearing. He doesn't even know this woman but he already hates her with all his guts
