New School Year English Learning: This Year, Make it a Habit! Start a New Habit with Manga. 'Langaku' and 'DMM Eikaiwa' Launch Highly Popular Collaboration Campaign Part 2 on April 1st!

Mantra Inc. (Headquarters: Bunkyo-ku, Tokyo; Representative Director: Shinnosuke Ishiwatari), which operates "Langaku," an app for extensive English reading with manga, will launch the second collaboration campaign with the online English conversation service "DMM Eikaiwa" for a limited period of one month starting April 1, 2026, coinciding with the new school year.

"DMM Eikaiwa" is an online English conversation service operated by DMM.com LLC (Headquarters: Minato-ku, Tokyo; PF Company CEO: Yusuke Muranaka, https://dmm-corp.com/, hereinafter "DMM") that offers 24/7 one-on-one lessons via PC, tablet, or smartphone (https://eikaiwa.dmm.com/). The first joint campaign, held in August 2025, received a great response, allowing many people to experience the "manga x English conversation" learning cycle. This time, to support more people in "starting to learn" at the beginning of April, a new opportunity to experience it has been prepared.

**■ Background of this Campaign: Why "Manga x English Conversation" now?**
The new school year and fiscal year are periods when learning motivation is particularly high. However, due to the busyness of new environments and the difficulty of maintaining motivation, English learning often ends up being a short-lived effort.

This collaboration provides an ideal learning cycle of **"input"** and **"output,"** which are essential for improving English proficiency, in a way that is easy to continue.

First, "Langaku" enables "reading and listening" input by enjoying favorite manga. The difficulty level (amount of English) can be adjusted according to the user's level, and Japanese versions or explanations can be displayed instantly for unknown parts, allowing users to immerse themselves in a large amount of English without stress. By transforming the pressure of "having to study" into the excitement of "wanting to read more" and "wanting to try this phrase," Langaku strongly supports the habituation of English.

Furthermore, "DMM Eikaiwa" provides "speaking" output through one-on-one lessons. The joy of being understood and new discoveries gained through actual conversations allow users to feel the learning effect and become a driving force for continuation.

By lowering the hurdle of learning through extensive manga reading and connecting it to practical opportunities with online English conversation, let's make English learning a fun habit starting in April.
