Guardian Angel's Smile
Sumi Serina is a kind-hearted girl with the Remedial Knights, she will do everything to be there for the masses whenever they are hurt.
Serina’s EX Skill (Intensive Care Set A) is simple to use but has many techniques related to it. Once she deploys a medkit for a single student to use, they will move towards the deployed medkit that will heal the student.
The rest of Serina’s kit revolves around survivability and healing.
Serina’s Basic Skill (Urgent Rescue Set B) passively heals Students with the lowest HP, potentially saving a Striker Student in a pinch.
Her Enhanced Skill (Ministering Angel) improves her Healing by increasing it by a decent percentage.
Meanwhile, Her Sub Skill (Guardian Angel’s Smile) improves all student's Crowd Control Resistance.
There aren't many changes to Serina in higher investments other than increased stats. However, at Unique Weapon Lvl 40, her Enhanced Skill (Ministering Angel+) will further increase her Healing with a flat boost.
- Cheap single target EX skill
- Can reposition a Single Student with EX Skill.
- Cost free healing
- No offensive utility
- Crowd Control Resistance is a dead stat (Most of the time)
EX SkillIntensive Care Set A
Serina drops a Medkit in the field, repositioning the student closest to the Medkit and healing them with a high amount of HP.
Serina’s EX Skill is extremely cheap to use and can be used to cycle through EX Skill cards faster. It can also reposition a single student to avoid an AoE attack.

Skill leveling priority: 3Guardian Angel's Smile
Serina’s Sub Skill provides Crowd Control Resistance to all Students.
Kind of a dead weight since CC is not very common in raids or general content.
Early game: Serina is a go-to healer during the early game due to her low-cost EX skill with reposition and cost free healing. This allows you to quickly cycle through your skills if needed. She is also accessible to all players due to her rarity being a 1*.
Early game alternatives:
Healers:Chinatsu,Hanae,Chinatsu,Nodoka (Hot Spring),Koharu
Students listed here are only some of the notable options available.
Late game (High Investment): Not much changes from the early game for Serina, she is still a reliable goto healer in general content and raids. She can also full heal Hieronymus Insane lantern when highly invested.

Total Assualt (Raids) Showcase
- Serina can be used in conjunction with Mutsuki in order to make proper use of her Basic Skill (Scorching Serenade). Allowing Mutsuki to have maximum damage with her landmines.
- Serina can be used in conjunction with Tsubaki to move her towards one edge into the screen and use her EX Skill (Deploy Tactical Shield)’s taunt to pull all enemies towards her. Allowing AOE Striker Students to finish them off with one blast. This is best utilized in Kaiten Raids.
While lacking in offensive capability and having a deadweight Sub Skill, Serina is your go to Healer for most content due to her cheap EX Skill cost and her Basic Skill’s ability to sustain your Striker Students on longer or difficult battles.
With an added benefit of a repositioning ability to her EX Skill, she can allow for strategies such as pulling enemies to a single spot via Tsubaki or allow Mutsuki to make full use of her landmines.
Serina remains a core healer for most content. Her healing in both her cheap EX Skill and Basic skill allows most students to survive for as long as possible.
How Much Should I Invest?: UE40, Once Serina reaches 2* she unlocks her Enhanced skill which improves her overall healing, and at UE40 would be a good stopping point as this unlocks her addtional healing in her Enhanced skill
