Shuna/Chronology

Forest Disturbance Arc
After Rimuru arrived at the scene where the Ogres were battling Rimuru's subordinates, she was the first to recognise his mask and come to the conclusion that he was related to the masked Majin that attacked their village with the Orcs.

However, after seeing how merciful Rimuru was being towards them even with his immense strength and the Ogres mercilessly attacking him without any explanation, she was also the first to judge that Rimuru had no relation with their assailant and stopped her brother before they fought to the death.

After the unnamed Benimaru decided to serve Rimuru and they were all about to be nameed, she was yet again the first to stop Rimuru from doing so due to the huge risks that came along with it. Despite her effort, however, this time, they were named anyway as Rimuru was ignorant of the fact that naming higher ranking monsters depletes significantly higher Magicules from the namer with a high risk of permanently losing a portion of the Magicules. Even so, things turned out well and Rimuru fully recovered from his sleep mode within three days without any permanent Magicule loss, by which time all six of them evolved into Kijin.

Shuna is very good at cooking, cleaning, and weaving, which is exactly what she utilised to be of use to Rimuru as his subordinate. She acquired the Unique Skills Analyst and Manufacturer which complement and optimise her already existing abilities, helping her become one of the key figures in Rimuru's future country's Department of Production. Alongside her, works the three dwarf brothers, Garm, Dord, and Myrd, and also Haruna and other Goblinas. It was because of her and Kurobe that Rimuru's village was able to acquire exceedingly better garments and armour before their battle against the Orc Lord.
