As fans of Demon Slayer: Kimetsu no Yaiba surely know, the Blue Spider Lily (青い彼岸花 aoi higanbana) was a crucial ingredient for the medicine developed by Muzan Kibutsuji's doctor to save his life. The flower was said to look like the Red Spider Lily (Lycoris radiata) but colored blue instead of red.

While a pure blue spider lily does not exist (or, at least, has not yet been discovered), there are spider lilies with blue coloring in them. The aptly named Electric Blue Spider Lily (Lycoris sprengeri) is mostly pink but it has blue streaks, with the degree of blue shading varying from flower to flower.

Last weekend, Japanese photographer Soubi 蒼灯 (@soubi_rose) found a remarkable specimen of Electric Blue Spider Lily with a gorgeous blend of pink and blue.

In full bloom, petals kissed by raindrops and resplendent in their radiance, the flowers begged for a photo opportunity, and Soubi was happy to comply. The photos quickly went viral after Soubi shared them on their Twitter account. At the time of writing, the Tweet has over 145,000 likes and 34,000 retweets.

The striking flowers elicited comments such as:

• "It's so beautiful. They have such a strong presence."
• "I feel like I've wandered into a fairy tale world. Truly balm for the eyes."
• "I can't believe there are such beautiful flowers in reality... I've never seen this before!"
• "It looks like a flower from an anime!"

Apparently, the photographer went to their neighborhood park looking for Red Spider Lillies but came across this stunning specimen instead.

It just goes to show that sometimes, the most remarkable and beautiful treasures of nature reveal themselves when you least expect them.

But if you do find a spider lily in the wild, whether it's red or electric blue, look but don't touch. Flowers in the lycoris genus are poisonous...
