Kasumi/Plot

Second Event Arc
During the 2nd event, Kasumi encountered Maple and Sally at the desert oasis. She probed them before she ran away, but they gave chase and wound up in a dungeon together. After being forced to clear the dungeon together, they became friends and separated to stay safe.

Later, Kasumi encountered mid-boss Sally and joined her in waiting for the 7th day. After Maple left the poison-filled depths of the cave, she sealed the entrance, and they played games together.

Guild Founding Arc
Kasumi accepted Maple's invitation to join Maple Tree.

Before the 3rd event, Kasumi gathered wool with Maple and Sally. After Maple acquired the [Sheep Eater] skill, Kasumi helped her trim her wool coat, and they collected plenty of wool.

Guild Competition Arc
During the 4th event, Kasumi raided other bases in groups with other members of Maple Tree.

While Maple was still defending the base, Kasumi had a rematch with Shin.

During the raid made by the Congregation of the Holy Swords, Kasumi kept Dred at bay while the others fought.

Rulership Arc
When Kasumi reached the 4th layer, she fell in love because it matched her hobby. She quickly raised her permit's rank as she completed missions and spent enough money to create 5 Maple Tree guilds.

After Kasumi's permit was promoted to rank 7, she gained access to a warehouse, fought Bewitched Sword・Yukari, and made it her weapon.

While Maple was sick, Kasumi and the other members of Maple Tree advanced to the 5th layer when it was released.

Kasumi joined Maple and Sally near the rain area. After they purchased umbrellas, they safely made their way to the rain area's boss and defeated it with a bit of effort.

Tower Arc
Kasumi, Chrome, Iz, Kanade, Mai, and Yui worked together to climb the 7th event's tower.

On the 5th floor, they changed their strategy because monsters with physical immunity became common. Kasumi and Kanade were separated from the rest of the group, and Kasumi acted as a tank and damage dealer until they escaped the mist.

When Maple and Sally had just finished the 7th floor, Kasumi and the others had already cleared the 9th floor and been defeated by the 10th floors' boss.

Companions Arc
While others explored the 7th layer, Kasumi returned to the 4th layer to find a companion that fit her aesthetics. After she found a new NPC and heard his story, she followed in his footsteps and completed several missions. For her effort, Maple was rewarded with a map to the Fog Valley in a Faraway Land and with some luck, she stumbled into it. After dying and trying to learn more, she explored the valley again. After imitating Maple to enter a den of snakes, Kasumi gained a tiny white snake companion she named Haku.
