Intro

Finally setting aside her identity as a sister, Halcyon Days Catherine now descends upon Orisries in her light vacation outfit, Kitty Handbag in hand—waiting shyly for you to join her days off! Join Lucia now to learn more about this Hero~

Catherine, a devoted sister of the Holy Church, is known for her kindness, always helping others, listening to confessions, and resolving their troubles. To everyone, her gentle beauty symbolizes the hope of the church. Regarded as a perfect sister, it is difficult to imagine her in any outfit other than her habit. Until one day, something unexpected happened—dressed in a light outfit that reveals her delicate shoulders and highlights her graceful figure, paired with a flowing, charming short skirt, Catherine stands shyly next to Commander. Although she was nudged into this outfit by her fellow sisters, Catherine still longs to spend a joyful holiday with the man she admires. Even though she isn't really used to such casual clothing and is feeling incredibly self-conscious, the mere thought of receiving Commander's praise makes her tail wag uncontrollably. "Commander, please don't stare at me like that... It's making me shy..."

EX Weapon Core 1

EX Weapon Effect

[Initiating Skill] At the beginning, reduce the DMG dealt by 43.44% for all of own Heroes and troops and all of enemy Heroes and troops for 3 turn(s). [Follow-up Skill] Starting from turn 5, after a basic attack from the troop, increase the DMG dealt by 43.44% for all of own Heroes and troops and all of enemy Heroes and troops for 1 turn(s). [Follow-up Skill] Starting from turn 5, after a basic attack from the troop, ignore 60% of the enemy's MDEF when attacking for self for 1 turn(s).

Lucia：The EX Weapon splits the battle into two phases—at the start, it reduces damage for both sides, but as soon as turn 5 arrives, it immediately shifts to increase damage for both sides while allowing her own troop to ignore the enemy's MDEF. This perfectly syncs with her skills, allowing her to dictate the pace of the entire battle.

Halcyon Days Catherine　Prayer of Romance > First Flutter, with EX Weapon Kitty Handbag With her skills and EX weapon, starting from turn 5, Halcyon Days Catherine becomes a consistent source of output with a boost on Magic DMG. She is the key to shifting the team's strategy.

Helen　Sharp-minded > Rear Support Helen can increase the troop damage output for the Hero with the highest MOR while consistently healing the entire team. This ensures that the team can withstand the early-game pressure until Halcyon Days Catherine grants the entire team an attack boost on turn 5.

Claire　Electromagnetic Wall > Prismatic Field Claire can withstand the enemy's attacks and stack her defense, easing the pressure on own team and perfectly compensating for the vulnerability caused by Halcyon Days Catherine's skill, Dating Tip, which makes the entire team more vulnerable to damage after turn 5.

Alternative Comps

Alternatively, try the team compositions below: Alfina + Halcyon Days Catherine + Catherine The classic Holy Church composition boosts Alfina's damage, continuously increasing the team's overall damage and chipping away at the enemy's health, while Catherine holds the line with her Bless effects and healing. Halcyon Days Catherine, now excelling at Dating Tip, strengthens early-game defense and thereby sets the pace for a strategy that focuses on defense in the early game and finishes the battle in the late game.

Lucia's Summary

Normally a gentle sister of the Holy Church who lends a patient ear to everyone's troubles, Halcyon Days Catherine reveals a completely different side of herself on the battlefield once she slips into her casual outfit. In the early game, she shields the entire team by reducing their damage taken. But once it is turn 5, everything changes—her Magic DMG and the damage boost on both sides all surge to their peak in one fell swoop. This seemingly shy sister knows exactly when to hold back and when to let loose. All you have to do is wait patiently until turn 5—and witness her unleash everything she has, holding nothing back!
