Full Title: After Being Banished For Having The Trash Skill "Gacha", I Came To My Senses And Broke Off Relations With My Selfish Childhood Friend ~After Getting An All Purpose Cheat Skill, I Aim For The Strongest Relaxing Slow Life!~
Crest is the fifth son of the Bahurst Duke, and the family pariah, hated and tormented by his father and elder brothers from the moment he could walk - because his mother died giving birth to him, and they see him as a murderer who escaped justice.
On his 15th birthday, he finally sees hope of a better future, as he had a prophetic dream that told him he would get a special skill, Gacha. When he goes to church to receive it, he gets it... but he discovers too late that the skill won't work, and it doesn't come with instructions on how to make it work. His father, incensed, exiles him to the [Lower World], something no one else has survived.
The very next day, the Pope sends a message to the King, which is shared in audition with the Ducal families: according to prophecy, the kingdom is under threat of a swarm of monsters, but God has sent counter-measures in the form of three very special skills: The Saint, belonging to Ellis Rifeld; The Hero, belonging to Minuet Mycelin... and Gacha, belonging to Crest Bahurst. Pandemonium erupts when Duke Bahurst reveals what he just did, and the King orders the retrieval of young Crest.
Unfortunately, it may be too late: Crest accidentally discovers how to make Gacha work as he hunts monsters in the [Lower World], and decides that, if the [Upper World] doesn't want him, then he's going to find himself quite comfortable living in his new place. And, if someone from there wants him to return? Tough shit, he's not going back, and damn the kingdom. Most of these numbnuts deserve it.
Associated Tropes:
- Aristocrats Are Evil: With the exception of the exiled Crest Bahurst, Minue Mycelian (who is a half-commoner Heroic Bastard) and possibly Duke Rifeld (who does appear to understand Enlightened Self-Interest and long-term plans), the aristocrats are all extremely short-sighted and care only about themselves, trampling whoever they have to for their own advancement.
- Blaming the Victim: Crest's father and four older brothers loved to blame him for the fact that they're all cartoonishly evil and the torment they heaped upon him by saying it's his fault as he murdered his own mother through the "crime" of being born, even though for the poor woman, Crest is the fifth son, and there's no mention how many daughters she birthed.
- When he's banished, Crest's fiancée Ellis called him an idiot for lying and said he deserves to be exiled unless he agrees to be her "dog" and allow himself to be treated as a slave. Crest responds to that by saying "SCREW YOU" and going full-tilt "Give me liberty, or give me death" to her confusion. She also made his academic career hell with slander and domestic abuse, blaming him for it by one-sidedly accusing him of cheating on her, all because his school mandated sparring partner happened to be a girl, and said girl just happens to have a bigger chest.
- When he's dressed down by the king, Duke Bahurst and Crest's four brothers blame him for "not trying hard enough to explain his skill" as the reason why they went and exiled him in the first place, even though Duke Bahurst made a point of shouting Crest down, in public, with the two other duke houses present, and all Crest's begging managed to accomplish was to get a throw-away sword that might just improve his chances of survival a tiny bit.
- Digging Yourself Deeper: Duke Bahurst. When he foolishly and impulsively banishes Crest to near certain death, he already started the process of dooming his house and perhaps his country, but his attempts to rectify things, at the request of the king who doesn't use his own forces for some reason, only make it all worse.
- He holds a meeting with his four remaining sons, looking for volunteers to go to the [Lower World] and recover Crest, knowing that they hate him as a result of being indoctrinated that "he murdered their mother" and if he returns, the King has made it clear that Crest is going to be the next duke, not any of them, and he's going to be deciding how to deal with them. Naturally, the first volunteer is the one who openly traumatized Crest and comes up with the "brilliant" plan to enslave him with a very illegal slave collar that's sure to be exposed right away even if it succeeds. Naturally, this alienates Crest further.
- The second "volunteer" is even more antagonistic, either trying to enslave Crest after beating him down first, and killing every one of his friends (novel) or just straight up murdering him (manga), and to improve his odds consumes a dangerous Super Serum, forcing Crest into a battle to the death.
- Maternal Death? Blame the Child!: The reason Crest's life was hell in the Bahurst house is that he committed the "crime" of daring to survive his mother's Death by Childbirth and every one of his male relatives looked at him like a cold-blooded murderer who escaped justice. His fiancée's Mad Love only made everything worse. It all ends with him being sentenced to death when he can't use his gods' given gift right away on command because it didn't come with instructions. When the written prophecy comes along that he was telling the truth and is a child favored by the gods, he's already fully alienated and even giving him the Bahurst duke title, letting him decide their punishment, isn't enough to get him back. The kingdom can burn to the ground for all he cares, since none of them ever came to his aid, all too happy to believe the worst, save Minuet, and she was powerless to help.
- Nice Job Fixing It, Villain: The sword Crest's brothers reluctantly give him after he begs for a weapon is what allows him to survive in the [Lower World] and discover that Gacha works by killing monsters, ensuring he can become a powerhouse - which is now very unlikely to use that power to benefit his birthplace.
- Only Friend: Before being sent to the [Lower World], Crest only had two people that cared for him - his maid Marnaas, and his school sparring partner Minuet.
- A Tragedy of Impulsiveness: Because of Duke Bahurt's prejudice, Crest is sentenced to death "for lying" about a prophetic dream, promising Crest's fiancée a week before the exile. When Ellis pays him a visit that night, offering him a Leonine Contract and he refuses, the duke goes back on his word and exiles the boy before dawn, and Ellis learns about it the very next day, then they're called in to meet with the king and given the prophecy... Oh, Crap!
