Helheim's Fruits



The fruit of Helheim (ヘルヘイムの果実) is the immature state of the Lockseeds, that grow in the Helheim Forest. They normally look like fruit, however if anyone wearing a Sengoku Driver picks them they will turn into mature Lockseeds.

As food
The Inves love both types of Lockseeds, regarding them as their favorite and only food, and will attempt to protect them if they are picked.

People who don't wear a Driver when entering Helheim or/and nearby the place where the Helheim crack portal was opened out of nowhere also seem tempted to eat Immature Lockseeds, and it takes outside help to make sure they don't eat it.

Effects
When a living being does eat a premature Lockseed, be it human or an animal, it quickly rewrites the creature's DNA and minds, as they will turn into an Inves, and in human cases like Ryoji Hase did, into an Inves in a Berserker State, where the Yggdrasill higher-ups then calls them "Category H" Inves; Inves that were formerly human. Confirmed Category H Inves are:
 * Yuya Sumii of Team Gaim; devoured an immature Lockseed and mutated into a Byakko Inves. He was unknowingly killed by Armored Rider Gaim.
 * An unnamed maintenance worker; devoured an immature Lockseed and mutated into the Komori Inves (Mutant). He was killed by Armored Riders Gaim and Ryugen.
 * Ryoji Hase of Team Raid Wild; devoured an immature Lockseed and mutated into a Hekija Inves. While Gaim tried to help Ryoji reclaim his humanity, he was murdered by New Generation Rider Sigurd when Gaim could not gather the mental fortitude to slay Ryoji.

Near-misses
Right (ToQ 1gou) almost ate a Helheim fruit when he first entered the forest, but was stopped by Kouta by shooting the fruit in Right's hand with the Musou Saber in Gun Mode.
 * Oren nom.jpg
 * A desperately hungry Oren Pierre Alfonzo also picked a fruit when he found himself trapped in the forest, but refrained from eating it at the last moment, remembering his survival training which taught him to not consume unknown flora in the field.

Safety
However, matured Lockseeds can be used as an alternative food source if a person holding a Lockseed inserts it in a Sengoku Driver like Kouta Kazuraba who used a Himawari Lockseed as a substitute for food.
