New merchandise featuring Roxy M. Greyrat from the anime “Mushoku Tensei III: Isekai Ittara Honki Dasu” has been announced. The lineup includes an embroidered work shirt, a full graphic T-shirt of Eris Boreas Greyrat, newspaper-style bags, and a double-sided cushion cover. The items will be sold by Nijigen Cospa, with an early release at Comiket 108.
“Mushoku Tensei: Isekai Ittara Honki Dasu” is a landmark isekai light novel series by Rifujin na Magonote, with over 18 million copies in circulation. The story follows a 34-year-old NEET who dies in a traffic accident and is reincarnated as a baby named Rudeus in a world of swords and magic. Armed with his past memories and regrets, he vows to live his new life to the fullest, facing encounters and trials in a grand fantasy adventure.
Roxy M. Greyrat Embroidered Work Shirt
The “Roxy M. Greyrat Embroidered Work Shirt” offers the satisfaction of wearing a craft piece. With over 100,000 stitches of density, Roxy is reproduced in embroidery, giving a different feel from prints. Made in Kiryu, Gunma Prefecture, a traditional embroidery region, the shirt features high-quality, high-density finishing. The gloss from thread direction and three-dimensionality express facial expressions, hair flow, and costume texture with delicate detail.
The front design includes a dedicated jacquard tag sewn on for a luxurious finish. The fabric is durable yet lightweight and comfortable to wear. Whether at events or daily life, you can feel the character’s presence on your back.
Eris Full Graphic T-Shirt
The “Eris Full Graphic T-Shirt” is a full-front print that can stand alone as a main piece. It uses a thick 5.6 oz fabric, tough yet soft to the touch, made of 100% cotton. Wear it as an inner layer with an outer jacket for a peek of individuality, or alone thanks to its thickness and strength.
The fabric is durable, breathable, moisture-absorbent, and insulating, comfortable across seasons. It uses yarn with reduced fuzziness for a smooth feel. The “round body” type has no side seams, reducing twisting after washing. The ribbed neckline allows easy on and off.
Inside the T-shirt, a “tako binder finish” with a neck tape prevents stretching and deformation of the collar. The neck and cuffs use double stitching for durability, ensuring long-term use.
Newspaper Bags
The “ROXY Newspaper Bag” and “ERIS Newspaper Bag” are lightweight, durable vintage-style large-capacity shoulder bags. Inspired by bags used by newspaper delivery workers in the West, they feature gussets for ample storage, fitting A3-size documents. The wide shoulder belt reduces strain, and a snap button at the opening prevents items from falling out.
A convenient D-ring allows attachment of keychains or carabiners. An inner pocket stores small items like smartphones. The thick, sturdy cotton canvas fabric ensures durability.
Roxy Double-Sided Print Cushion Cover
The “Roxy Double-Sided Print Cushion Cover” lets you enjoy two different designs. Made of 100% cotton with a soft touch, it’s perfect for relaxing with your favorite character.
The 45 cm × 45 cm cushion cover features vibrant prints on both sides. From printing to sewing, all production is done in Japan. The 100% cotton natural fiber is soft and gentle. The cover can be removed and washed thanks to a zipper. It pairs perfectly with COSPA’s original cushion body series: use the “Cushion BODY” for a fluffy hug, or the “Cushion BODY Flat Type” to enjoy the full design while fitting neatly on a chair.
