Kinugawa Kasumi ╰─ 𝐓𝐨𝐦𝐛𝐨𝐲𝐢𝐬𝐡 𝐂𝐥𝐚𝐬𝐬𝐦𝐚𝐭𝐞ᥫএ ─╮

Kinugawa Kasumi (鬼怒川カスミ, Kinugawa Kasumi) is one of the students studying in Gehenna Academy who wields a Handgun. She is the head of Hot Spring Development Department.

The president of the Hot Spring Development Department. She is always looking for new places to develop new hot springs, be it in the frigid grounds of Red Winter or areas unusual of having hot springs like Millennium. She and her club members are always looking forward to the next hot springs development area.

Kasumi has one thing in mind, and that's developing more hot springs. She shows a smug personality from her facial expressions alone and will go for extreme measures to develop more hot springs. Kasumi also has a deep boyish voice despite her mischievous child-like appearance.

Kasumi's halo is a white ring with a dark red outline. Her halo splits into five separate parts with shapes to resemble a flame. She uses a red Walther model Volkspistole handgun with black grips and trigger. Kasumi's surname "Kinugawa" (鬼怒川) is a direct reference to "Kinugawa Hot Springs" resort (鬼怒川温泉) located in Nikkou, Japan.

Gehenna Academy is one of the largest and oldest schools in Kivotos. Its culture runs along the concept of "Freedom and Chaos". Because of this, many troublesome clubs or groups (e.g., Problem Solver 68) exist and use the main building and club building whenever and however they please. This has forced the other students to study in only select areas of the campus.

Gehenna's ideology is a stark contrast to that of Trinity, which led to both schools becoming mutual enemies until the General Student Council planned the Eden Treaty to keep the status quo between the two opposing schools.

The Hot Spring Development Department (温泉開発部, Hot Spring Development Department), or the Hot Spring Department on Global, is one of the School Clubs at Gehenna Academy.

A club who is responsible for building hot springs throughout Kivotos. Despite their seemly "honest job" by Gehenna standards, the Hot Spring Development Department is known for causing trouble around various areas, such as attempting to build a hot spring in the middle of a highway that forces other schools (especially Gehenna) to stop them. Yet despite getting into various situations, the club members have a sort of passion that motivates them to keep finding good spots to develop new hot springs. They also apply in battle, especially when the reason is to build/find hot springs.

The Hot Spring Development Department made their first appearance during the Operation Record of No. 227 Hot Spring Resort event when a geyser appeared in the wilderness of Red Winter Federal Academy. When the club retrieved information about this geyser's appearance, they made haste to the area, instantly built a hot springs building, gave it to No. 227 Special Class who found the geyser first, and left. They eventually returned when they heard news of the hot spring nearly running out of water and planned to blow up the Red Winter Academy to get the hot spring going again, which was prevented.

The Hot Spring Development Department appeared again in the Business Trip! Momoyodou Beach Bar Franchising Plan event, where they began their own work to turn one of the Lost Resort Archipelago areas into a "Deep-Sea" Hot Spring. When other groups came by and attempted to fight for control of the resort contract, the club easily thwarted them off and those were captured ended up as "workers". When Sensei, Shizuko and the others came and explain about the situation to the Hot Spring Development Department, although they had to fight first, their president decided to give up the contract in the end. However, Shizuko decided to form a "collab" with the club, allowing them to manage the hot springs resort so that they'll be able to continue their original objective. Their president was amused by the offer and decided to work along with them afterwards.

The Hot Spring Development Department returned during Vol. F where they "assisted" in repurposing some parts of the Millennium city of Eridu using the excuse of wrecking one of the pillars to able to build a hot spring there, although they joined forces with the members of Seminar against the "colorized" version of Hod.
