Bell Cranel is a young adventurer with white hair and red eyes, a look often likened to a rabbit. He is considered extremely cute by many female characters. His typical attire includes lightweight armor, a hip-length brown coat featuring a small black patch above the right chest, a long-sleeved black shirt, black pants, a beige belt with a silver buckle, and brown shin-high boots.
His personality is marked by humility, straightforwardness, bravery, and shyness. He cares deeply for those around him, especially his goddess Hestia and Familia members, viewing them as family due to the death of his grandfather. Initially aspiring to become an adventurer to pick up girls and start a harem, influenced by his grandfather's advice, his motivations shifted after being saved from a minotaur by Ais Wallenstein. He fell in love with her and became determined to grow stronger to stand by her side. This event also left him with a fear of minotaurs, which he eventually overcame.
He is known for immense kindness and compassion, frequently risking his well-being to help others even in perilous situations, earning the respect of many gods and adventurers as well as the affection of numerous women. His trusting nature sometimes leads to him being tricked, such as by Naaza and Liliruca Arde, though he easily forgives and holds no grudges. He is a poor liar and cannot keep secrets, but possesses a notable ability to read people's emotions and loneliness.
Despite a timid appearance, Bell has a strong will. His feelings for Ais granted him the skill Liaris Freese, which accelerates his growth based on the strength of his emotions and makes him immune to charm effects. He is resilient and determined, enduring rigorous training and overcoming challenges to achieve his goals. After his loss against Asterius and ascension to Level 4, he becomes calmer and more level-headed, focusing on creating a world where both people and Xenos can coexist and on defeating Asterius.
Bell was born to a member of the Zeus Familia and Meteria of the Hera Familia after their defeat by the One Eyed Black Dragon. His mother gave him to Zeus before dying, and Zeus raised him in a rural mountain village as his grandson. Growing up listening to hero stories from Zeus, Bell was inspired to become a hero. He was nearly killed by a goblin as a child but saved by his grandfather. After his grandfather's presumed death, Bell traveled to Orario to become an adventurer. Rejected by numerous Familia, he was eventually invited by Hestia to join her Familia as its first member.
His abilities include superior physical prowess from achieving SS and SSS stats at each level, making him stronger than typical adventurers of his level. He possesses exceptional strength, agility, and combat skills, enabling him to defeat opponents above his level. He learned the magic Firebolt from a grimoire given by Syr Flova, which he can use without a chant and often combines with his Argonaut skill for increased damage.
His skills include Liaris Freese, accelerating his growth based on his feelings for Ais; Argonaut, allowing him to charge attacks or movements, with a full charge taking four minutes after reaching Level 4; and Ox Slayer, enhancing his abilities against bull-type monsters. Development abilities include Luck, improving his fortune; Abnormal Resistance, negating poison and other abnormalities; and Escape, increasing his speed when fleeing.
Bell's relationships are extensive. He views Hestia as family and is deeply loyal to her, though he does not reciprocate her romantic feelings. He is in love with Ais Wallenstein, and his desire to become worthy of her drives his growth. He has close bonds with Familia members like Lili, whom he views as a little sister; Welf Crozzo, seen as an older brother; and Haruhime, whom he rescued and shares a love for fairy tales with. He also trusts and respects Ryuu Lion, who trains him, and Eina Tulle, his dungeon adviser. His kindness extends to Xenos like Wiene, whom he protects, leading to initial ostracization in Orario.
After rejecting Syr Flova's confession, later revealed to be the goddess Freya, he becomes wary of rejecting women's feelings due to Freya's subsequent actions. He continues to act based on his emotions, often helping others without expectation of reward, which endears him to many. His journey includes reaching Level 5 and gaining the alias Rabbit Foot after being known as Little Rookie.
