The Hashiras were walking through Mount Natagumo, looking for any demons. They then encountered Rui, The spider demon and LowerMoon 5..

Uzui tries to hit Rui but Rui kicks Uzui back. Rengoku then tries to burn Rui but Rui blocks the flame with his BDA. Mitsuri tries to cut at Rui but Rui shoves her away. Obanai then tries to whack Rui with his fake snake but Rui cuts it. Shinobu then tries to summon butterflies to attack Rui but Rui cuts all the butterflies. Sanemi then tries to run at Rui to capture him but Rui quickly moves out the way. Muichiro then summons a mist cloud to hopefully make Rui dizzy but Rui blows away the mist. Giyuu then tries to drown Rui with his water breathing but Rui dodges that. And lastly Gyomei then tries to crush Rui but Rui cuts the stone into thirds. They thought it was all over until..they hear the sound of soft, light breathing above them.. they open their eyes and look up to find.. another demon.. it was also a spider demon but it was.. a little girl? The little demon was in a web.. asleep.. Then they wonder.. who that little girl was..
