### Recommended Discounted Titles: 1. **'Nobunaga no Shinobi' Vol. 1 (Author: Naoki Shigeno)** - **Synopsis:** Chidori, a ninja girl, dreams of helping Oda Nobunaga achieve 'Tenka Fubu' (unifying the country)! A new milestone for the 4-panel prince Naoki Shigeno, this Sengoku GAG manga revolutionizes the format. - **Comment by Bookstore Staff M:** While historical 4-panel manga have existed, few portray Nobunaga's battle with such dynamic yet delicate detail. Shigeno's ability to balance classic 4-panel punchlines with the tragedies of the battlefield is the hallmark of a veteran creator.

2. **'Sensei no Ojikan' Vol. 1 (Author: Tamami Momose)** - **Synopsis:** The hit series by Tamami Momose! Meet Mika Suzuki, a 148cm-tall, baby-faced 27-year-old Japanese teacher. Her students are full of personality, making every day a fun incident. - **Comment by Bookstore Staff M:** This series shows that 'dramas' don't always need big events. It's a pioneer of 'daily-life moe' 4-panel manga focused on dialogue. Yet, its school setting aligns it with the lineage of mainstream TV school dramas. It proves that school stories in 4-panel manga can be a legitimate evolution of the genre, even without high-stakes drama.
