The Tears of Diablos (ディアボロスの 雫しずく) also known as Beads of Diablos in English Dub are magical pills medicine that contain the incredible power derived from the blood of the demon, Diablos.

These medicine pills were created from the remains of the demon Diablos, which was severed by the Three Heroes. The cultists greedily wanted the demons power and began to perform experiments with its remains. To their research discovery, the demon remains possessed an incredible vitality and was able to instinctively move and regenerate.

From then on, they created what would be known as the "Tears of Diablos" and their different types from the incredible life energy that contained within Diablos Cells. The medicine pills still had side effects, but unlike before, it was effective on men now as well. Nelson was one of the original 12 members of the cult "Knights of Rounds" who helped, organized, and collaborated in the creation of these pills and their derivatives.

Types of Diablos Tears
Over time, the Cult has used these drugs to support their endeavors, but the source of their true strength lies elsewhere as they engineered these Tears from Diablos' life force on the flesh and blood to increase mana power. But, come with the risk of destroying one's body and mind if they aren't already strong.

After spent numerous years for researching and experimenting on its remains for ages, they were able to developed various types of pills to increase the magical power of its organization and its members. So far, there are 2 types of Diablos tears have been known.

Tears of Diablos Normal
The "Tears of Diablos" refer to Red pills (赤あか い 錠剤じょうざい) that are unfinished products created using Diablos Cells. These pills were produced in large quantities, despite having strong side effects during development. They are primarily distributed to the powerful members of the Cult of Diablos, particularly the First and Second Children, as well as the "12 Knights of Rounds."

However, these pills have significant flaws. The side effects are too potent for the human body to handle, even for those within the Cult who possess the necessary requisites to control such magical power. As a result, the red pills are considered semi-failed experiments by the Cult.

The pills serve as temporary enhancements, boosting the abilities of high-ranking servants by increasing their magic power, body size, and muscle mass. However, they do not provide the desired result of immortality that the Cult sought. Individuals such as Grease, Zenon Griffey, and Gettan have used these pills to pursue their goals.

Pearls of Diablos
On the other hand, the Pearls of Diablos are special pills that grant immense demonic magical power and maintain vitality, effectively providing immortality to those who consume them. These pills are exclusively reserved for the twelve highest-ranking members of the Cult known as "The Knights of Rounds."

Unlike the normal red pills, the production of the Pearls is challenging, and the number of drops is extremely limited due to the scarcity of Diablos Cells. Precisely twelve drops are produced each year, corresponding to the exact number of members in the "Knights of Rounds."

Furthermore, these Pearls are not perfect, as the power and longevity of the individual who consumes them will significantly diminish if they are not ingested annually. The Pearls are created using two main ingredients: the cultivated Diablos Cells obtained from the bodies of demons and the blood of descendants of heroes.

Potential Power and Side Effect
These pills cannot be consumed by normal people with little magical power, be it a human, elf or half-beast, as these pills contain tremendous demonic power. If they consume it, it would deform the one who eats them until they break under this outburst of strength and die from the tremendous supercharged magical power that eventually lead the self-destruct on their body. But those in the "Knights of Rounds" are different, because only those who can manipulate this devastating power by controlling it have the right privilege of joining the Rounds.

These pills grant great raw demonic magical power, which increases the strength and speed of the Diablos cult members who consume them with the possible side effect of metamorphosis mutations depending on race and surpass all limitations, also a rapid regeneration and high resistance to inflicted pain called "Third Awakening" (覚醒者サード). Until now, it was unknown what else it grants at the level of use of spells and enchantment, apart from the fact that its effects were temporary.

In general, a part of these pills can exert a great increase in magical power. But, by eating many of these, it can causes whoever ingests them undergoes a metamorphic transformation in his entire body, sometimes even fusing with the weapons they carry.

Another effect of these pills is that its enhanced effects didn't last long, whether a few or many that are taken, they have a limited period of functional time. The moment its effects ended, whoever consumed it would return to their normal state, not to mention being exhausted by the immense power exerted by the pill, leaving them with little strength to fight. As seen in the case of Gettan after being defeated by John Smith who despite his altered body condition by consuming many of these pills, he returned to his normal appearance, but with little strength to fight plus the exhaustion he had which ultimately led him to his death due to the serious injuries he sustained.
