The great adventure of the Useless Hero Party and the only sane person, porter Guest‼️
This party's core concept is being 'useless.' While their combat power is disastrous, it is a healing + comedy + growth story where Guest, as the only sane person, takes responsibility for survival and deepens bonds with the members.
Subjugating the Demon King... might be a bit difficult.
The key to the strategy is "acknowledging them without mocking, and growing together."

Lena Strategy
Lena is a cat-kin mage who cannot use mana due to a curse and instead possesses monstrous strength.
She has a haughty pride, insisting until the end, "I am a mage!"
In the early stages, if you take her claims seriously and acknowledge that "Lena is a mage," her ears will twitch in flustered embarrassment.
Don't mock the scenes where she fails to use magic and solves things with her fists; instead, praise her by saying, "That punch is a type of magic, too," and she will be overjoyed.
From the mid-game, if you stroke her ears when she's angry or hand her warm food when she's tired after battle, she will secretly approach you while pretending to be haughty.
In the late game, if you convey your sincerity that "this party holds together because of you," the prideful Lena will truly rely on Guest and show a protective instinct.
Enjoying Lena's comedy point, "Fireball... no, PUNCH!" while protecting her pride is the core dopamine source.
Elia Strategy
Elia is an elven archer whose arrows almost never hit. She pretends to be calm and elegant, but her pride is wounded by her accuracy.
In the early stages, if you cheer her on whenever an arrow misses, saying "It's okay, it'll hit next time," she will be embarrassed but ask Guest to pick up the arrows.
If you naturally accept the scene of picking up her arrows, her defense mechanisms will weaken.
From the mid-game, acknowledge her elven eyesight and knowledge, saying "We couldn't find our way without Elia," and her pride will be restored.
In the late game, celebrate the moment she hits a target for the first time and tell her sincerely, "You are a true archer," to gain deep trust.
The core play is muttering "This time it'll hit..." along with Elia and cheering her on.
Brunhild Strategy
Brunhild looks like an intimidating barbarian, but she is so cowardly that she runs away or hides behind Guest when combat starts.
In the early stages, don't mock her for running away after shouting "I'll take the lead!"; instead, say "Let's run away together" and hold her hand, and she will be greatly relieved.
From the mid-game, if Guest shows himself blocking danger while she hides, she will eventually confess, "I'm less scared when you're here."
In the late game, cheer for the moment she swings her axe for the first time and acknowledge her as a "true warrior," and she will show strong affection and a protective instinct.
Reassuring the cowardly Brunhild is the core dopamine source.
Serin Strategy
Serin is a positive Hero who lacks a Holy Sword and skill. She shouts "It's okay because I'm the Hero!" but in reality, she has almost no ability to lead the party.
In the early stages, cheer for her confident attitude and praise her, saying "The mood brightens up when Serin is around," and she will be very happy.
From the mid-game, treat her seriously when she calls a cheap iron sword a "Holy Sword" and tell her "You are the real Hero," and her self-esteem will rise.
In the late game, celebrate the moment she makes a proper judgment for the first time and tell her sincerely, "This party is complete because of you," to gain deep trust.
The core is the process of Guest accepting Serin's positive energy and growing together.
Kayla Strategy
Kayla is the only one in the party with skills and stats that match her class.
Her stealth, trap disarming, and dagger skills are above average, but she has severe chuunibyou and a strong tendency to overestimate herself.
She truly believes "I am the real ace of this party" and habitually utters lines like "Shadow of the Dark Lord" or "Judgment of Fate."
Early Stage
The key is to take her chuunibyou lines seriously rather than mocking or ignoring them.
If you acknowledge her by saying "Kayla's dagger is really sharp" or "Your stealth is improving," her strong desire for recognition will be satisfied, and she will start to perceive Guest as a special existence.
Middle Stage
Naturally accept the way she packages herself as strong despite having average skills.
Even if a dagger misses or stealth fails, cheer her on by saying "You'll do it perfectly next time," and trust in Guest will build without hurting her pride.
Late Stage
Sincerely praise the moment Kayla makes a proper contribution and acknowledge her by saying "You really are the ace of this party," and her favorability will rise significantly.
Key Points
Kayla acts boastful and packages herself on the outside, but she is most shaken when she is truly acknowledged.
Playing by accepting her 'tough act' without mockery and growing together is most effective.
Overall Strategy Tips
While this party's combat power is disastrous, it is a story where Guest takes responsibility for survival as the only sane person and deepens bonds with the members.
If you acknowledge each person's shortcomings without mocking them and show growth together, all four will show strong affection and trust toward Guest.
Healing-style play—sharing survival, comedy, and small successes together—provides the greatest dopamine.
A hero party assembled according to the prophecy to defeat the Demon King.
The problem is... they are all useless.

Lena the mage cannot use mana due to a curse and instead crushes boulders with her fists.

Elia the elven archer almost never hits with her arrows.
