Hilstara

A mercenary who once fought alongside Simon during the later stages of the war with the Incubus King. Despite her occupation she is a noble soul who is willing to do the right thing without pay so long as it helps people both in the short and long term.

Ignoring the succubi, Hilstara is one of the most notably bisexual characters in the cast. She actively expresses interest in other women in the harem, including Aka, Megail, and Carina. She also plays the field a bit in Eustrin with Galvia. As expected of her personality, however, she isn't pushy about this, giving Carina space when the idea made her uncomfortable.

Story
As a young officer, she fought in Zirantia during the final phase of the war with The Incubus King where she met Simon. Disenchanted with the whole Chosen of Ivala system, she joined the Redlight Mercenaries:

She joins the party in Stineford, after some chat with her in the Noble District Pub. To recruit her, you have to talk with her again and accept her proposal. Meet her at the mine to induct her into the party. Try to do that before you take part in any fights to maximize the experience that she is able to receive.

She kept a cautious, professional relationship with Simon for many years, but he says to Robin that he trusts her, and given that it's coming from Simon it is high praise indeed. In the Devil's Pass, she confesses her feelings to Simon, that back in her youth:

Skills
Synergy skills can be used in battle only if both Hilstara and the specified character are present in the active party.

Starting equipment
Weapon: Steel Axe.
 * Axes

Off-hand: Iron Shield.
 * Shields

Headgear: Iron Helm.
 * Helms

Bodygear: Iron Armor.
 * Armor

Accessory: Gauntlets.
 * Common accessories
 * Anti-sexual accessories

Tactics
The clear tank of the game: she's blessed to start with a Steel Axe because honestly her attack growth is abysmal. Her choice of weapon means that she is also more likely to miss than the others. Both her stats and her equipment provoke that her actions happen very near the end of the turn. Shieldwall makes most enemies attack her and she has multiple party wide buffs that double as minor healing spells. She compensates her defects (to a certain degree at least) with her AoE buffer skills: Hold the line! is twice as effective as Tactical eye for clarity not to mention the delicious defensive buffs. She's got two utility skills for synergy, Encourage which allows her to increase the damage from another physical attacker (Aka/Varia probably), and Bash which is the only way to apply confusion until you get Robin and Qum's Synergy skill Disrupt and can also stun. Honestly, her attack on average is barely stronger than mages so she is pretty much a full on support character. A highly specialized one at that.

One use for Hilstara is as a shield wall. With Mammoth Plate armor, a Mammoth Shield and Hilstara's Helm, her AGI will be 1 (so she will always be going last), but most melee attacks will literally bounce off her and do no damage. Even bosses can't do much more than scratch her armor's paint, and with Shieldwall up, they are very likely to target her (the defense boost makes her even more stronger). Also, since the 0.28.x versions this skill is activated before any enemy attacks, so the rest of the party members are protected in turn 1, too. The only problem is that her magical defense isn't nearly as high, and most bosses have some form of magic attack – or worse, an AoE attack that ignores Provoke.

Depending of your playing style, you'd rather have a strong attacker instead of Hilstara's anemic offense (for comparison at least). But that doesn't mean that she can get the job done, even in solo actions.

Relationship points
Maximum affection is 100, at which you can have a conversation with the harem girl that will lock her affection there.

Though Hilstara tends to like "good" choices, for the most part she's an easy relationship. Just pay attention to her and her quests, and have sex with her when you get the chance. Hilstara seems to favor military investments, since that's her specialty.

Relationships
Megail: Though they aren't on good terms at first, Hilstara and Megail grow to have strong relationship. On their trip while the party is split up, they have multiple conversations and gain more respect for each other. A less important conversation leads them to have a threesome scene with Simon, where Megail is receptive to Hilstara's advances. It is unknown if Hilstara knows the truth about Megail's past, but based on what she has said, it would only increase her respect for her.

Aka: The two of them are good friends, having many common topics to bond over. Hilstara is interested in Aka sexually and Aka is at least willing to experiment with her. They don't seem to have been involved much since that scene, but it doesn't seem to have harmed their friendship in any way.

Yarra: Though Hilstara doesn't particularly dislike Yarra, being pretty laid-back about things, she also keeps her distance due to her old habits about succubi. Much later in the game, Hilstara seems to have overcome this bias and they have a good conversation and a threesome scene together.

Carina: Hilstara is supportive of Carina, even though they two of them don't agree on theology. Though Hilstara has some interest in Carina, when Carina refuses Hilstara backs off. The two of them seem to be on generally good terms and often have similar perspectives as human Ardans.

Lynine: Shortly after joining the harem, Lynine goes to Hilstara for advice about dealing with succubi. Hilstara provides it and they also have a scene that proves Lynine is just sensitive to everything. Aside from this, the two of them seem to be on good terms but haven't interacted much.

Galvia: While the party is in Eustrin, these two catch each other's eyes and they have a brief fling. Both being older, experienced women, they aren't head-over-heels, just enjoying each other. They seem to part on very good terms.
