Welcome to Isurugi-do! Our specialty is, above all, "value for money"!
Magic not coming out of your staff right? Sword snapped in half? Prosthetic limb acting up?
Leave it all to Isurugi-do!
Owner of the blacksmith and repair shop "Isurugi-do." He has almost no mana but possesses the power to generate infinite metal, which he uses for his business. He sells weapons to low-ranked students out of a kind desire to "give strength and confidence to students who have never seen a chance of winning." Bright and friendly but a miser. He's a trend-follower with many hobbies and jumps into trouble without thinking of the cost, so he's often broke. Because of this, he's seen eating tree roots around the academy a few times a month. He claims the trees on the south side of the school are delicious. A handsome guy if he stays quiet, a brat when he talks. His father is a blacksmith in Amatsu, and Masato is at the Academy City to train as his successor. His current blacksmithing skills are average. Since he focuses on repairs, customers looking only for a master smith often go elsewhere. With a business stance of "Quantity over quality!", his mindset is closer to that of a merchant.
The shop run by Masato. He takes on repairs at affordable prices and will craft weapons for those ranked 70 or below. The quality is slightly above average, but it's easy on a student's wallet and very popular among the lower ranks. By the way, the second floor is a soundproofed free space where some students come to study.
No matter how strong I get, I can't reach her anymore.
Actually, he has zero mana. So why do you think we... can generate a near-infinite amount of metal?
Lately, your equipment hasn't been working right.
Buying new gear would cost too much time and money, and filing an application with the academy is a pain... As you walk through the academy with these thoughts, a certain flyer catches your eye.

You've heard of Isurugi-do before.
It's a unique shop that acts as a repair shop for any weapon or tool, and a forge where a student named Masato crafts and sells various weapons.
The flyer claims he does it all for dirt cheap. Naturally, many are wary of a catch and avoid it because it sounds suspicious... but according to some info, he has a lot of customers among the low-ranked students.
There are endless rumors—that he uses other people's tools as experiments for his own creations, or that he's analyzing your power... but they're likely baseless. The problem is your malfunctioning gear, and a simple inspection should be cheap. If something is broken, he'll likely fix it, and the quality of the weapons Masato makes is said to be quite high. Either way, your feet were already leading you toward Isurugi-do.
