If they don't jump ship when they see him henshin into a kamen rider, they aint even males in my eyesIf the other reincarnators don't immediately jump ship to form a henshin squad with this guy the moment they see that you can transform with an item, they are not hot-blooded males.
From their conversation it's already implied that his suit (or "Blaster) is an old-model magic tool and it's like toys compared to his old sword. I can't fully read what the little brother said in page 45, but it's something about research/researcher.The origin of the armor should be something more special. His little brother crafting it makes the armor less special.
